The eyes are really powerful in this image, but that's except the nose the only thing that's fully rendered. It's a shame the black of the fur doesn't have this kind of shading. I think that if you add some more texture to the hair and maybe give the scar a bit more attention this piece will truly bring forward what you are going for. I'm not wanting to drag you down in any way or sound offensive, but I feel like I'm looking at a work in progress piece rather than a finished one.
If you decide go back to it, then please show me the result! I'm really curious because I'm confident you can make this image even more beautiful than it already is!
