Looks a little boxy in the transition between the front and side of his body. I'm guessing you're working in ortho views alot, but sometimes you just have to break away from front and side views and be a sculptor in perspective. The legs might be a little short, and the toes look kind of strange all splayed out like that (it might also have something to do with there only being 3), but I think this is a really great start to a character model! Good work! Do you have plans to animate it?
