your concept is good, I've seen some nice pictures of colorful things hanging, but I think the execution fail here a bit, maybe is the composition, the bg seems to make the whole scene kind of busy and the picture looks slightly oversharpened.
I love the composition and color of this, although I don't think that the focus is spot on. I also would have cropped the top row, so that the colors weren't duplicated.
Great color and clarity. I think it would have been even more effective if the horizontal lines of the rack were leveled a bit more. To me they seem higher on the left. I do like the photo though. 7
