Please tell me you're giving him a beam chainsaw? This looks great so far. The one thing that I can spot that looks a bit off seems to be his hand, but other people have already commented on that. Try to make the thumb curve inward a bit starting at the point where it's joint would be, maybe?
By the way, this character combo is completely expected from you, hahaha. It works really well, though.
