I think this is cropped a little too closely around the wheel. Feels a bit too claustrophobic.

Hard to find a focual point.

this is great

A friend of mine who is an amateur photographer would go crazy over this shot, with all it's converging and diverging lines and arcs. I like simple, though, the simpler the better. However, I thought I'd pass one that some folks will think this is terrific and I'm giving you good marks on that account.
