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.

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

Hello, here are my attempts, I tried to keep the proportion right and find the right perspective at the same time, very hard. And one of each took me so mush time to draw. It's really hard to keep the lines clean, I redrew so many times. I would appreciate some feedback. Thank you.

re-visiting the ribcage assignment. adding a little bit of muscle study too.

Here's my ribcage assignment. I think I draw some of them too big. Any feedbacks will be greatly appreciated.

The pelvis area is so challenging. Happy to take critiques - Thanks

Here is my bunch of drawings for this lesson, I've used both skelly and assignment photos for this lesson. I'm using landmarks as a guidelines for anges of the torso bones, but still not always sure if I defined the position right!

Hey Eveline, For the most part you did pretty well. In some of the poses I noticed that you are stiffening up the poses a bit by not pushing the ribcage enough. Also, make sure you understand that the pelvis usually points down away from the ribcage. This causes a counter balance to the body. I did some quick sketches to show you what I'm talking about, I hope it helps :)
