Heheh, delicious work! :)

you've got a nice sense of perspective, and the head looks absolutely awesome. Fantastic use of dynamism and expression with the head, even the whole upper body.

I'm not quite sure about the legs though. *looks again* actually, the calves and feet are great (I can't draw feet for all the gold in Kentucky) it's the quads that I think you could improve upon, since lord knows the rest is dang near perfect. I think they look a little down, like they've been deflated; your work, I think, is better with more detail, and obviously this is just a sketch.

Still admiring your work, by the way.

great pic
