I see these. and they're cool. But I feel as if you can push the composition a bit more. as it is, and I noticed from all your work too is they're very straight lines. It's like the line of action on all your poses are pretty straight lines.
I would like to see you play with contraposto a bit more, but also would love to see you play with eye flow. They're mostly straight forward top/bottom, and there is no drama. no tension. no action. Just, here I am. I would love to see you play with their silhouettes a bit, and create stronger poses. They're nice work, and you have wonderful vision but you can do so much more with these.
I don't know. one day I might get into professor mode and just draw over your stuff to show you what I mean, but i know how much I hated that when my professor did that to me; and I know as an artist, I hate it when people draw over my work but still.. you have a hell of a lot of potential. Better than some of my students.
