Hey Lucas, You put a lot of movement in the spine which is good, but you have the spine cutting into the ribcage in both of these drawings. Remember, the thorasic spine curves with the back of the ribcage, yours is not. Think about what the spine is doing from a side view, that will help figure out whats happening. I did a quick sketch over your drawings to show you what I mean, I hope it helps :)

Hi @Gabriel Kahn, the vertebrae drawings are looking great! I'll try to look for things to improve on: - The crosscontours on the spine are looking off. I think you would benefit from drawing it again, and if you don't know how to draw crosscontours on a curving cylinder, let me know and I'll try to explain👍 Cheers!

Hi @viny, I think these studies are really nice! Good anatomy, good gesture, good structure! - You have the tapering from lumbar to cervical, which is great, but I think you might be making the spine a little too thick. - I would pay some more attention to the sacrum. Its proportions don't look right in some drawings. Hope this helps :) Keep up the good work!

@valix3 each lesson has to be downloaded individually.

@Daniel Mayerhofer the next assignment is located in the lesson, "How to Draw the Spine."

I was confused by this too. But judging by this image it seems clear to me that the 6th would be completely invisible since it's so far buried by that ligament he mentioned. So I'm going to assume the 7th is the first one we can see, at the top of the diamond. The second, more prominent one, must be the 1st thoracic.

:(

Hey Tony, I haven't gotten to this assignment myself yet so maybe I would have better feedback at that point. However, one thing I'm seeing is that you clearly define the front plane of the ribcage, but not really the back. In a few of Stan's examples I just glanced over, he didn't draw the back plane either. However, he doesn't draw it because he knows the perspective by heart and just skips putting it in. In your case, I think you're unsure about where that back plane actually is. For you, I would try to "draw through" and sketch in the back plane of the ribcage, even when looking at it from the front view. Once you have the back plane, you can give it a centerline and you'll know that the spine has to follow that. At the moment, it seems like your spines are just floating somewhere inside the ribcages, rather than being anchored to the rib cage's back plane centerline. I made this simplified egg example for you that hopefully makes sense. The leftmost form is just an egg. The middle is an egg with a little of the back carved off. You can see the green centerline follows the form. That centerline is what you would attach the edge of the spine to. The third form is just with the spine added. Hope that helps. Maybe I can help more after I do that assignment.

looks great to me!
