i like that eye. the mouth looks good too. i think that if you gave this guy a nice, but simple snow base your score would jump. (just try using baking powder)
I think you did a good job and I think 4.7 is a ridiculously low rating. The teeth are nicely finished. The eyes are pretty good and the blood is decent. I think you deserve a 6.5, but I round up because you're taking such a pounding here. I would recommend you adding stripe of black accross the baack so it will look more like a wolf. For some ideas you might want to check out a bunch of wolf-riders I have at http://www.aamortgagellc.com/download/me/images/goblins/wolf-riders.jpg
They're not the greatest, but they might give you an idea of how to improve the pattern on your wolf's coat.
