I can't find much wrong with this. The curving aspect is nice, but It's a shame about the lighting. Maybe the brighness and contrast could have been manipulated in another way.
This is a nice image that could have benefited greatly by some different choices in cropping, IMHO. I would have concentrated our attention on the great potential for symmetry here by cropping out most of the bottom, a bit more from the top & some from the sides with a bit more from the right- enough to get rid of that overblown top right corner plus bring that strong vertical line right down the middle.
