Interesting, seems pretty cool how the wolf character has a look to them as if they were transforming either into a wolf or getting ready to become a human again. However given that is how she is meant to look as wolf, just makes it rather neat. Makes me think of shiny Pokemon in a way.
While the coloring of the fur all over makes it easy to tell where things are, I feel it might help on this drawing if you had added a line to her front legs as you had with her head. While I can tell that they are separate due to the fur design, it just looks odd.
Overall, neat, although a background would not be too bad.
