Just like a small tipp; When drawing wolves or animals, try to put his neck more where his jaw ends, and make it long. Animals have intensly shapely bodies, you have the head pretty much perfect, but if you just look at a picture of a wild wolf, I bet you'll be able to draw them like a pro in like a day.
Kudos to the face, it's ten times better then I could do. I suck at animals. -_-;;
