This is pretty nice, but the leg on the left (his right) looks like is is rubber.  It appears to stretch, like the foot was nailed to the ground as opposed to flexing at the knee. The change in perspective would change how the cuff hangs. The legs all, in all seem a bit odd in their proportions. Also, I think the foot is a bit far over to manage this kind of pose. Also, I prefer the shading above the waist to that on the legs and below.

All-in-all though, super first post!
