Assignment: Draw the Rib Cage

Construct a Robo Skelly rib cage and the pelvis using the bucket method. Try to be as accurate as you can with them. Don’t just draw a generic rib cage shape in there. Look for clues from landmarks and muscle attachments that will tell you exactly where the rib cage is.

I decided to continue my progress in the Marvel course (at least I know what Ryan is saying in the penciling section), but my anatomy knowledge is still really shallow, try to take it more seriously this time after some mileage in the perspective course and the basic course. 1st -2nd pic = my assignment and some ribcage in different angle 3rd = drawing along the video is placing 4th = after the critique video, did some tracing to know which ribs = which point i m drawing for the rib cage, coz I tried to straighten the organic curves that the ribcage has. 5th = after the how to draw ... video, decided to follow along and invent some angle Question: 1. I am not that comfortable with the top down view(the muscular dude in the 4th pic) of the ribcage, especially on how the thoracic arch shape changes. 2. The thickness of the muscle also confused me when I was doing the 4th pic. I am simply just guessing it and see how Stan did it in the critique. 3. I noticed some artists simply draw a circle instead of the egg shape for the rib cage, I guess thats a stylized choice. e.g. cartoon?

All of these look awesome. Drawing the ribcage in perspective is tricky but you got it. I’m not sure you would see the underside of the ribs in that one pose on the 4th image. I took a screenshot from Proko’s Skele app to show an example of the ribs at that angle.

🥺 Alright... I am somehow confuse.... And it's not envy, but it makes me sad when I see that the tasks sent here are much better than what I did, and I don't know what I'm doing wrong. But well... I'll watch the shoulder lesson and the critique videos in a moment for see what did I do wrong

Here is my 1st attempt on the assignment! Did some corrections after watching the demos but still haven’t seen the critique video.

Here are my tracings for this assignment. I'm planning to go back and draw them freehand, and I'd welcome any critiques before I do!

Had to watch how to draw rib cage first. Only on 7th try I realized that I had to double check my proportions. Always measure, my comrades!

harder tan it looks to find the right shape for the rib cage and it's dimensions compared to the pelvis/head

Good everning, This is mine practice:

Your drawings remind me of George Bridgman's work! He has a wild linework style but his proportions and understanding of anatomy are top notch. When you're studying anatomy, you want to be as accurate as possible with proportions. You have the shape and slant of the ribcage correct, but keep in mind these general proportional rules: Ribcage is 1.5 heads tall, 1.25 heads wide, 1 head deep. The thoracic arch is the midway point between the pit of the neck and the bottom of the ribcage. Good luck :)

Hello! Here are my attempts, I feel I struggled the most with the perspective, specially with the back of the ribcage like #9, any feedback is appreciated!

Somehow struggled more with the rib cage than the pelvis even though I was using the 3d model for help, definitely would love feedback on this one.

Here are some of my work. I found #3,5,8 are particularly hard to draw as the land marks are hidden and the poses are quite dynamic. Please give any advice if there's somewhere weird. Thank you.

The breast is pulled upward so I identify the 5th and 10th ribs to place the rib cage. Sugeestions are welcomed.

Good guess! I think you are right :D Not sure if I would worry too much about those specific ribs, at least I personally wouldn't. I think you can improve the shape of the ribcage. It looks flat. Pay attention to the connection between the neck (cylinder) and how it connects with the ribcage. I think that should help with the 3d effect. Complicated pose, good work!

ı think it doesnt extremely matter what bones they exactly are since theyre not LANDMARKS. SIMPLIFYING and thinkin more practically will improve youre drawing more
