Well let's see, taking a good look at this and at references... (in particular, this picture of him) His one arm and hand, as someone else pointed out, is very "human" at the moment. It doesn't resemble the thin claw or the thick paw he has on either forearm. Otherwise, his neck, it is kind of thick, although the actual technique on it is really good, so it would be a shame to undo that now I think it might be survivable like that, so it's your call.

I will say that his face is completely wonderful in every which way. I would not change that for any reasons at all. Its curves and the expression are perfect, really~
