The quality on this is rather low. Try shooting in RAW or don't enlarge. I think you may have sharpened it too much too. I Think this might be a more interesting picture if you had the numbers on the ground in the shot as well.
I like the low perspective, and the use of the lines. It looks a little bit over-sharpened though. It also might be nice to try cropping out the trees and extras along the top.
