Nice use of lines for a repetitive pattern, and nice bold colours, but overall not a very good photo. Maybe needed to play around with the perspective a bit more (either flat perspective to get straight lines, or wider angle to warp the lines for more interest?)
This isn't an awful image, but considering the other entries and the effort they made, I'm going to score it a tad bit lower just because I can see you didn't put a whole lot of effort into the challenge. Holler at me if you like, but it won't make your photo any more exciting. I am impressed however at your collection of books. It definitely recalls the works of Dr. Suess.
A fox and a cat, Mr. Brown and some feet,
Green eggs and ham down on Mulberry street.
But where are Horton, the Lorax and Whos,
The Sneetches, the Grinch and Bartholomew?
The shot is a bit uninspired for me. In a challenge full of creative and fun entries, this one is lacking. Even using a more dramatic pose or lighting might have helped.
