This looks pretty good. It's kind of difficult to see the features of the wolf, especially the eyes. Was that done on purpose? I feel like some of the proportions are off. Perhaps the snout could be a bit longer, and the neck a bit less thick. Though I'm not really sure because I'm not familiar with the proportions of a wolf.
The snarling mouth of the wolf gives it a threatening appearance, but the eye doesn't as much. On the other hand, the fur looks well drawn, and gives off a bit of a windswept appearance. The color chosen for the fur makes it a bit more realistic. However bad you think it may be, it still looks better than anything I could ever draw. Great job!
