I gave this a 6 - really like the extreme close up and the great focus on the eye. And I like how the green in the background matches! You did a terrific job cloning out the eye boogie - I wish I could do that for my cat routinely, in 3D. There is no end to his goop.
I really like this shot - I find the juxtaposition of the green eye and swath of green in the background interesting. I do think it would have scored better if the whole background more or less matched the eye. Harley is adorable. I love kitties!
6 - Beautiful colored eyes. I know this is 640, but like to have seen it 'bigger', somehow. Like the matching green in the composition but wonder if it dominates a little too much. A little sharper (maybe not so close/reduce blur/who knows) and attention paid to the reflection in the eye, make this better in my opinion. Like the potential. Like the thin slits too.
