Tools used : Adobe Photoshop CS5 and mouse

I found the sketch to this sitting on my hard driveef
d decided to finish it.
Initially I made it "cartoonish" but then started shading and ended up with this.

Any comments and suggestions as to what I should changefnd add is appreciated, as I feel as if something's missing, but can't figure out what atm; also I think the eyes are too small?

WIP2 ears remade and some other stuff:
