hey what's up everybody rob Marzullo

here Rams to do comics welcome back so

today's lesson is actually a free sample

from my how to improve your figure

drawing course this is less than two of

the course it's the full lesson so it

allow you to really kind of try it out

to think about my teaching style and if

you've watched the channel here then you

probably already got a good idea of that

so this will give you the opportunity to

let you know what this course is about

and there'll be links in the description

box below to both udemy and my gum roads

that you can pick whatever platform you

feel most comfortable with and also keep

in mind that you're getting a reduced

rate by acting now but it will be

increasing each month until it reaches

its full price so I hope you enjoy this

lesson and I hope you'll check out the

course let me know what you think and I

will talk to you soon

so in this next lesson I'm going to show

you how to break down arms we'll just

systematically go through parts of the

body but I think it's important to

realize how you can individually

separate certain components of the body

and then reassemble them together it's

that it's what the way that I found has

helped me the most with my favorite

drawing so when doing the arm I look for

some basic shapes this is one that I see

for the shoulder and for the bicep I

generally see something like this so

more of a football shape the tricep

something like this or from this

particular angle anyways and then for

the forearm I generally will see this

muscle here and kind of a cylinder shape

like this so on and so forth and then we

dissemble the hand and we'll be getting

into hands up later on in this course so

essentially that's kind of how I place

some of the shapes now this takes a bit

of practice to even probably get to that

level where you're comfortable just

throwing in those shapes

so what I'll first do is show you how I

got to that or you know how I get to

that comfort level basically if you're

starting out you might want to start

more with a circle align another circle

another line and another circle and this

represents the shoulder the elbow

and the rest something to keep in mind

is that generally the rest will line up

to the shoulder and then you'll add the

hand on afterwards so you know we're

starting the this basic guide you can

give direction to your next party or

illustration and then from here you'll

add cylinders like so like so so you

know you can see it's pretty crude but

it helps us to you know see a little bit

further into what we're doing so I'll

set this one off to the side I'll

actually if you copy this and move this

over okay so if I was to take this now

and refine it a bit and look into the

arm illustration a bit more you can just

soft erase that down or use a light

table or whatever method you're working

with and then you can start to place

these shapes that I Illustrated over

here and you know obviously this is a

different angle or I don't know if you

could tell but it is a different angle

than the one off to the right there so

basically we have to envision what those

shapes will look like over here and the

part that you need to study you know you

learn how to draw this way but then also

you need to study the way that Anatomy

works in the way that muscles work

muscles will always pull from one area

of the drawing or arm and they'll

connect to other areas and some parts

will overlap and intersect and some

parts will go behind other parts so

that's where studying your Anatomy will

teach you that now the other thing that

you need to be aware of because say I'm

just drawing the perimeter shape of the

arm now so I'm trying to give it some

form I'm not trying to draw into the

anatomy too much but I am placing some

of the muscles as I go here so let's say

I get it to about there and let's say I

didn't draw them this shape of the bicep

yet so I just have mainly the silhouette

where

I think it's important to always study

your silhouettes I think it's another

way to commit a lot of this stuff to

memory so say I just did that and I

didn't get into the musculature too much

on the inside of the drawing yet it's

also important to study the thickness so

after you get the silhouette also study

the the thickness of the overall shapes

so here to break them down like this and

you get this by studying the shadows off

a photo so we'll say it goes something

like this so just with those simple

lines that I added there we're able to

give a lot more of a dimensional look to

that arm you know then you can start to

perceive where maybe light hits on this

part of the arm as well and bounce light

and all that fun stuff but you know we

won't get too much into that because

it's almost a whole nother series of

videos and topics but so by placing just

some of these smaller shadow shapes like

that you can really start to get a more

dimensional feel to the arm so I think

it's important to do that

so you want to study the overall

silhouette you want to study the way

that shadows react and give it depth but

that all starts with these basic crude

shapes let me go ahead and take this

scale it down move it over okay so the

other thing is just to log in a lot of

different poses so let's do the back of

the arm

so we'll start again with the very basic

rudimentary building blocks so let's say

that this arm what I'm perceiving just

so you know even though I've only put

down a circle align a circle line I'm

actually perceiving that the already in

my mind that it's going this way and if

the arm is going back out and away from

camera just a little bit so I just want

to illustrate that for you because it's

you know you want to start envisioning

that as early on as you can in the

process so now a larger circle for the

shoulder will do a cylinder up top

the top of the arm I'll even round the

cylinder in the way that I would

perceive it connecting to the shoulder

so I'm already starting to illustrate

that visual guide for myself and then

here I want to perceive that it's going

away from camera

I'll taper the cylinder just a bit and I

try to always make sure that the

cylinder for the form is the equal

distance from this base cylinder to the

top of the shoulder again I said like I

said before if you were to raise this it

would actually meet the top of the

shoulder then you would add the hand on

so just keep in mind I'll see a lot of

illustrations and it seems like the

forms are always too short so let's make

sure to add that enough and also the

common mistake as well is not to taper

the wrist as far as it need be okay so

now let's go ahead and take this to the

next stage and let's add a little bit

more I'll even add a bit of a wedge

shape for the hand but we won't get into

detail on the hand yet because I want to

save that for another lesson so we got

the elbow back here and let's go ahead

and copy this I'll shrink it down first

move it over copy and paste move that

back over okay so now let's go ahead and

give us a little bit more form so on

this next stage we can start to figure

out the shapes a little bit more and

overtop this will do again that kind of

oblong shape like this for the shoulder

we make sure to make the shoulder a good

size larger in width and height than the

rest of the arm it's another thing I

notice a lot is people tend to draw the

shoulders a bit small so from back here

we're going to see the tricep that'll be

like this now the tricep will generally

kind of come out word if I was to draw

it off to the side it would almost be

shaped

like this somewhat that it splits down

the back goes up one side is up higher

generally the inside portion or not join

with it as the inside portion closest to

the let so you know just kind of that

shape there will draw that in so

depending on how defined you're trying

to make a character look or muscular you

could start out very light with this if

you're not doing something as stylized

or as as intense as comic book

illustration the elbow I like to just

kind of keep with that circle it's got a

bit of a downward point to it and it

kind of tapers up it's also a good point

for where to draw the the line that you

see in the back of the arm that kind of

meets down to the back of the wrist

so I would actually need to tilt this

hand a bit more and the forearm

generally is larger and wider at the top

here and then tapers down pretty heavily

and you get a bit of this muscle around

the side there and the wrist right at

the very end flattens back out so you

know it's it's just knowing this about

Anatomy and studying the way the muscles

go and what direction they had you know

and obviously this isn't a perfect

sketch I don't know if there's a such

thing but you just keep doing it doing

it and you'll you'll get a better feel

for you know what you like to see in

your own drawings and how much of a

stylized representation you want versus

realism and you know the more time you

put in the more realistic it's generally

going to get so if you keep soft erasing

this and you keep coming back with a new

perspective and draw overtop and

generally you're going to get closer and

closer now especially if you're studying

from reference if you're just kind of

eyeballing it like I'm doing here then

you you know you might tend to distort

things and give it a more stylized look

that's when I'm after being more in the

comic illustration so I'm okay with that

but you know there's no harm in studying

reference and recreating this stuff it's

how you learn so you know like one of

the tricky parts is right here how the

the tricep comes down and around I think

it meets somewhere around in here you

know and I don't want to draw this

overly segment it as I'm already

starting to do but I do want to

illustrate some of the parts away the

muscles head and the shoulder does this

tricky kind of thing where they almost

rotate up and back around so it comes

down further in between the bicep and

tricep and it goes up and around kind of

like this and meet to the back and you

know a good way to perceive all of this

is that all of its interconnected that

everything you know kind of segues into

another thing in a muscle group two

muscle group so say so something like

that and that would give us a kind of an

overly straight down but a back view of

an arm and I don't know that you would

actually see as much of the bicep as

I've drawn here

I think the tricep would kind of get in

the way more you'd see less of this

bicep let's go ahead and select this and

scale it down and put it next to our our

base template there okay so I want to

show you one more before we conclude

this lesson and I want to show you

basically another way of looking at it

so I've shown you how you can break down

the shapes with a quick line for a

shadow here and I've showed you how a

couple representations of how you would

work up from the basic form now the

other thing I want to show you to get in

the habit of is to break down the shapes

even a step further so let's go ahead

and take another arm position like this

so I'm just going to kind of skip

talking about the beginning stages and

you can just watch me rough this out or

hopefully you're following along and

we'll get these basic shapes into place

but then what I'll do now is I'll go

ahead and go right to

designing this in more of a 3d type

fashion you know we have to remember

that we're creating 2d images on a 2d

surface but we're trying to envision 3d

we're trying to make things look very

dimensional and we're basically cheating

you know it's a bit of a tomfoolery if

you will I don't think I've ever used

that term before but so basically you

know you're trying to really make it

look like it's three dimension even

though it's not now one way to do that

is to actually get in here and do as

many three-dimensional lines as you can

so really draw these lines and put you

know pretend like you're looking at

something in a 3d program it's

oftentimes well I'll tell my students to

study a little bit of 3d even though

you're working as an illustrator and

you're trying to create things in a 2d

space I recommend that you study 3d

programs and there's some free ones out

there that you can get into without you

know dedicating your life savings to it

but you'll get in the habit of looking

at three you know things like this in a

3d space which is a I think helps your

visualization process so you go like

this you know you kind of draw as much

of it in a 3d kind of grid as you can

and then also you break certain parts

down and you do your studies and you say

okay this this muscle right here you

know looking at photos or whatever you

got to do how would it look in a 3d

space and you can shade and and kind of

visualize that better by segmenting

these certain areas and breaking them

down so I guess you're just idolizing

parts of the body and really focusing on

it and then you know studying this

muscle here how does this react and how

thick is it to the base and help then

how quickly does it taper off this way

but I think these little lines that help

you draw in 3d space let me solve trace

this down again and I'll illustrate that

even further I think it really helps you

to see that and break that down so I'll

draw it again just kind of quickly here

I'll do a little bit of line weight just

to

further illustrated you see i'm almost

making things look a little too angular

and a few spots but i'm doing that

intentionally because i want to really

kind of you know push that direction

that i'm going for visually the depth of

these segmented muscles so something

like that there's a few more muscle

strands away it goes around like this

and you know again this isn't entirely

about accuracy as much as i'm trying to

explain the process in which i break

things down and study you know so the

bicep and the way it connects to the

shoulder you're generally not going to

have it this segmented less you're a

really big bodybuilder or something but

but for the sake of studies it's not a

bad thing so we'll just kind of over

illustrate that will show the separation

from the shoulder muscles this again

will show those those kind of

three-dimensional lines 3d lines will

even have them taper off to just this

muscle group like this you know i almost

picture like we're drawing a colossus

from x-men and we see the lines on them

if you're familiar with who that even is

but maybe maybe not but by doing this

you know you're really painting the

picture that each one of these areas are

segmented and that they're rounded but

they have a bit of depth to them so

again that's what this line here is for

just line to the back of the elbow sign

to the bottom part of the forearm and

you know you can shade these in if you

want and keep in mind all these art

files will be supplied with the course

so they're available here for download

so that you can follow along and study

these

probably already knew that but just in

case you didn't so just like that so in

and again you know each part so even

though you don't want to get in the

habit of over segmenting your natural

drawings your your typical figure

drawings it's okay when you're studying

because it kind of reinforces these

shapes in your mind then you can go back

and soften them up so you know obviously

don't recommend doing this if you're

drawing up you know a real life drawing

or anything like that but but for

studying it's more than adequate so like

this and again just really trying to

visually get the idea of the shape of

these these muscles of this arm so I do

this quite a bit for my studies I just

feel like it's it really helps me to

understand it and then from here just

save these you know save them in your

sketchbook save them in your computer

under you know titles and things so that

you can access them and that way if you

do spend your time really doing some

intense studies you can pull from that

reference you can remember where you're

at as an illustrator and what things

were clicking mentally for you because

that happens at times there's times you

go back and look at some year old

working like man I was doing well with

drawing hands or feet they're in the

night I somehow forgot that and I don't

know why that occurs but it's just

something that that does happen chances

are what it probably is when you were

doing well with it previously you were

inspired because inspiration is a big

part of drawing any of this stuff so

there you go that's how it break down

and do some studies for for some various

arm poses all right so that'll conclude

this lesson next we'll head over to

studying the legs and breaking those

down with shapes as well so let's

continue on

[Music]
