I hope I don't sound rude by this, and I do love the way you drew the werewolf, but the perspective for the crossbow looks really weird, in my opinion. It doesn't seem like the gun turns at the right angle in certain spots, like there's a twist in the main shaft and the left... arm? (is the the name for it?) The front, center part also seems like it's off center, but that might just be me.
Once again, hope I don't sound rude by posting this. It's a great piece, so very nice work!
