I really like your unusual composition with the diagonal lines, which has given a fan shape effect. A few suggestions: Using PhotoFiltre take the gamma slider down to 80 and it will fix the over exposure, add some contrast, and maybe just try cropping some of the bottom off and watch this image come alive.
What a great idea to 'see' beyond the usual perspective. I am surprised you managed to obtain sharp depth of field despite using f4.7, heck I have a lot to learn.
