Hey guys, welcome to Proko.
In this critique episode, and I’ll be talking about common issue I saw in a lot of peoples
arm bone drawings.
It’s a very important part of learning to draw Anatomy because it’s usually the thing
you start with when drawing the forms of the body.
I’ll focus on just one critique here, but in the premium episode I go over a bunch more
common issues and drawings that you guys submitted.
So, this critique is for Sherry Wang’s assignments.
Thanks for sending them in Sherry.
Sherry, I'm noticing two things with you.
One, very, very important, and that is that you're not looking for the landmarks of the
bones that we can see on the surface in order to place the bones.
I think you're just trying to draw bone shapes on top of the arm, but not really looking
for clues to where to actually put them.
And the things that I'm seeing that really give that away are, like, look at these bony
areas.
Right in here is the elbow, the ulna.
That's right on the surface.
I mean, there's nothing on top of your elbow, no muscle, there's a very thin tendon, but
it doesn't add any bulk to it.
So the ulna you put in there doesn't even touch the surface, it's not even close.
So that's way too thin in there.
Same thing in the wrist.
I mean, look at how thin you're making those bones.
As soon as some kind of force is put onto those bones, they would snap.
Like I said earlier, the wrist is mostly bone, and so that entire thickness you're seeing
in there, you're gonna have to put bone in there.
Same thing in here.
Look, that is bone right in there, but you're not showing that with the shape of the ulna.
And then the epicondyles, I didn't think you really looked for the placement, which it
would be, like, right there.
That little V shape that you saw in the shadow, that's the tendinous sheet, the little stringy
sheet that you see on inside there, leading right up to the epicondyle.
Same thing down here.
There's the elbow, but I'm not seeing any form in there for the ulna.
So don't forget about landmarks.
Landmarks are one of the most important parts of anatomy.
They're really, really good clues to where everything is.
You know, that's where the muscles attach and that's the most consistent thing on the
human body.
You know, muscles and tendons, the shapes will change and the size relationships will
change, sometimes the muscle belly is longer, sometimes a tendon's longer, sometimes they'll
attach a little bit off of where they should be, but those bony landmarks, they're the
most consistent thing on the human body.
And so learning those and using those to place things is really important.
So please don't disregard that.
I really suggest going back to these and trying again and maybe just identify the landmarks.
Just go through and just kinda put little dots on where the landmarks are.
That alone will be a really good exercise.
With that, I'm gonna end it.
Thank you guys for submitting your critiques.
I always have a great time looking at your assignments.
It's great to see that you guys are doing them and you're following along with the course.
If you haven't submitted any assignments, it's not too late, you can always submit these
to the Facebook group and the community will give you the critiques.
And of course, watch...you're watching these videos, so you can see all the common mistakes
and you can make sure that you avoid them as well.
So all right, thank you guys very much, I'll see you next time.
