Hi @Yi Yu, I spent a lot of time looking through these, and they are really nice! Here are some things that might help: - I like to lightly indicate the It band, to make sure that the muscle fibers are going to the right spot. In your second image, first drawing, the gluteus maximus is a little small. I think this is because of how you placed the great trochanter and It band. - The fat of a butt hangs down past the muscle fiber. Eventhough the fat with it´s gluteal fold defines the boarder of the form, I like to lightly indicate the actual muscle as well, just to make sure that everythings going to right spot and to train my anatomy X-ray vision I hope this helps :)

The exercises you did drawing the skeletons I like them a lot. The first one I feel you could draw a box or a bucket to indicate the tilt of the pelvis. But overall they're very good. The tracing exercises I feel that you're misplacing the landmarks. When doing this kind of exercises is very important to look for the bone clues that show through the skin. When drawing legs look first for the greater trochanters, the head of the fibula, the lateral and medial condyles and the maleolus. You can also see almost the length of the tibia through the skin. Then, after you find those clues you complete what you can't see with your knowledge. Remember that if you're drawing bones that are almost leaving or out of the body, you're going too far. Keep drawing and best regards

I think they are great. Nice job. The 3D feel-like is very good due to the shading.

Great job.
