Wolf Portrait

I did this last year after school began...
I attempt to make a realistic picture by trying to add texture to the wolf so it would liike fuzzy all over. Of course it didnt turn out the way I wished it did...
I was actually lookin at a real wolf picture when I was drawing this, but after I finished the eyes, I did it base off my memory, so it didnt come out looking like the picture. Although the face is a bit, it's one of my best work ^^

I need some advice in creating the texture... -.-
