Ahh... The simple beauty of watercolor. I don't see anything wrong with this piece. The wolf looks pretty proportionate (the eye and the ear in the foreground may be a tad bit small, but I could be mistaken). The sky is lovely. I like the layered texture of the fur. The only thing I would be tempted to add to the wolf is a scattering of black hairs on top of the head and on the edges of the ears for extra contrast, but I don't see anything that I would change. Beautiful work.
