I really love the colors, but I also like the design. It's not generic, yet not so far out there I just look at it, unbelieving. I think my one criticism would be that her tail seems a little too big for her body, even with perspective in mind. When I was looking at the thumbnail, I thought the tail was her leg, but that's not really your fault.

Overall, I love that peaceful look on her face. I think this is a wonderful image.
