The ears, nose, muzzle, and eye sockets are all awesome. As is the fade of the hair towards the center of the brow.
The short hair is a bit odd to see on a werewolf, but it is very nice to look at and not an unreasonable choice. Reminds me of the hair of a breed like a Boston terrier, or perhaps a bear.
The resolution of the mouth seems to be at odds with the very crisp lines that you see elsewhere in the image, it could probably use some sharpening.
The area behind the teeth, what we would call the jowls on a person, do not give off a canine feeling, that combined with the hair reminds me much more of a werebear. And actually as I look at some images of black bears roaring, the likeliness increases. This is not a bad thing, just something that I have noticed. The more I study your image the more I think would make a fantastic werebear with the ears turned towards us slightly. Again those ears are awesome.
Great image again.
