Hmmmm, Spike on vacation?>.<
Anyway, I find that the picture has quite a good balance to it, and you're anatomy isn't bad at all. The hands however could afford to be more accurate, but this is something that takes some long term mastery, and nothing to stress. Also, perhaps the arms could be definded a little more, they look a little like sticks. Other than that, bang up job!
Hah hah hah hah(evil laugh (ignore this))
