These look absolutely stunning! If I had to nitpick I would say that sometimes the boxes don't seem to have a correct perspective. LIke in 8 of 10 the upper left figure has a hip box that has a little bit of a strange perspective issue. That being said, this looks amazing; good stuff!

I like how expressive the face is, I would watch out for the line quality which seems to be a little bit scratchy, proko has a video on how to correctly hold a pencil, it's worth a watch! Good luck on your art!

I feel like there's good solidity and structure. I would try to bend the lines on the boxes and make them more curved when necessary, some of these figures look a bit stiff. But other than that I think that you're doing a good job :D

I love the movement on these! Personally I would just try to make the lines a bit tidier, the lines on some of these are a bit messy in my opinion. Other than that, keep up the great work :D

I think you're on the right track. I would personally try to improve the connection between the two spheres of the bean, I think the drawing would improve a lot with more continuity and gesture between the spheres . Keep up the good work!
