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
