Thanks for the comments, guys! I appreciate the tips, and looking at it I can definatley see that the anatomy is pretty bad, the legs look pretty crooked and weird. I'm no master of anatomy though, but I could probably do it better.

I'm glad you like the idea too! Keep the suggestions coming, I'm going to try to improve the things you've pointed out so far until the next piece. It was fun to draw, and I'd like the next one to be bigger and more thought out.
