This is really lovely. I'd like to make a suggestion: if you could add some highlights to the wolf's fur, it would help it to stand out more. It's too close in value to the background. This is an illustrator's "trick," and I think it would push it from "great" to "outstanding". Hope you find this helpful. I know people don't make suggestions on dA, but this is SO close to being a knock-out, I had to say something.
