I think the facial expression is what makes this skin so great, he doesnt seem happy nor angry, just a man doing what he must (for evil powers, I presume). The details are fantastic, and I like the look of his cloak. The alienesque bone-like things growing on his arms looks very well.
I think it looks very balanced, nothing stands out from the rest of the skin. Good work, and good luck!
This skin is really impressive...This guy is a mage,or wizard of some sort judging by his staff, but unlike all the other mages i've seen, he actaully has bulging muscles, making him appear even better..
