I like it. Im a fan of werewolves. But there are things that could be improved upon.
The feet look alittle to big. Even if its supposed to be abit deformed.
The tail could be abit longer and fluffier.
WoW!
You know, most of the pixel arts I try to do don't get good because I cant do fur. I can't use that hairy texture. And you used it perfectly on that pic. The anatomy is very perfect for me, and his face is very... facy (xD)... no more comments.
5/5!
Great sprite of an werewolf... dithering is done very well, so is the color selection, and the rest of the details that I have noted. Props. If it is animated, that would be even better.
