This is a REALLY close up view - very neat to see the intricacies of the eye. I do think that it may suffer from being somewhat out of focus (although this may have been a conscious artistic choice). But it's a very cool shot. The highlights are a little blown out, but I love the web of textures and colors.
I think this is an eyeball iris macro... but I could be wrong. It has an other-worldly appearance. It appears to be cropped heavily from the original, and when that happens, along with resizing, you lose a lot of quality and resolution. The centering of the subject makes for a rather flat image; perhaps choosing a composition where the pupil is in the top left or top right corner, with the colors of the iris coming out from it in diagonals would make it a bit more dynamic. The lights reflected in the pupil are distracting, which pulls the attention away from the rest of the image. I think you were on the right track with the idea, but the lack of technical and creative proficiency in the idea's execution will probably have you falling short of a score you might hope to achieve. It is not something most voters would hang on their walls. I wish you luck in future challenges...don't give up!! :)
Whew! Too close for me. Feel like I'm entering Mordor! On the serious side, I'm trying to figure out if I'm looking at something modified using Photoshop "art" filters - the either natural or induced "noise" detracts from the image, IMHO.
Certainly meets the challenge. I'm not sure this will do well though, it's not the most pleasing looking eye, and it also looks like you blew up a photo bigger than its original resolution to get this close.
