they look awesome! all of them (even wormtail)! the entire stag's head loks awesome, the dog looks good as a whole, the strong legs of the rat made him look "stronger", and the werewolf is a-m-a-z-i-n-g! really. loved the werewolf. your're really good with anatomy and hair/fur!
the colors also looks nice (liked ho we can see brighter and darker fur), although maybe I would like a different color for the background, because the pic is so brown (but it probably was your intention)!
