I like all the oval shapes your composition has created.
My only wish is that the DOF had been a bit greater to show the front headlight more sharp. Easy to do with the Rebel-G (or 500N as we know it in Europe).
I'm surprised you haven't had any comments on this photo before.
this is a great black and white photo; very beautiful shot; great close-up view, nice compsition, and great reflection on the metallic surface; the only possible suggestion for improvement or change would be to experiment with sepia tone or another tone
