This is an interesting abstract. The imperfections hold my attention more than a perfectly round object would have. The lighting creates depth within the picture. Good job. This would be a good subject to play around with and come up with different looks.
Eh, it looks really yellow/brown. I like the subject, it's a new idea, however, it's placed right in the center and really does not make the photo interesting there. I do like your cropping though, keeping everything even. Perhaps it is the light, but it seems soft to me and when it looks like that is paper, I'd like to see crisp edges. Score: 4
