Less shadows in the eye would've been nice. Also.. I personally would've darkened the fur around the eye just to make the eye stick out. The picture isn't as clear as most. But really, its a great picture. Nice idea. Very colorful. I like it.
The blues in the eye are very nice. A bit more lighting in the top right quadrant of the eye would enhance this photo further. As it is right now, you end up with a comple black void for a section of the phot whcih then starts to pick up color on the outer edge.
