Wow, these are so dynamic! With all those crazy leg poses, I really like how none of them look detached (which is something I struggle with). Your line art is so clean, but I'd be really interested in seeing what you could do with a little more detail.
Thanks for the comments. I'm really just trying to focus on getting the proportions and structure right. I'm trying to avoid focusing on details at the moment until I really have the proportions and structure right. This one is about as detailed as I'm going at the moment.
