too abstract and too little detail for my personal liking. I however will not mark you down because I do not like your photo. I look at the photo in it's own merit. And that is not bad at all.
hmm intersting to look at nice colors, crisp image, exciting, but I don't feel that it realy met the challenge. I can see the Z but it's a little weak IMO. Other that that this is a great image.. Nice job
