Your picture is intereting to look at. The colors and focus are good. I think I would have liked it better if more of the wheels were showing instead of being cropped off.
Seems to need a litle more or better lightning or longer exposure, then you can increase the contrast without getting this white spots on the front wheel (on the left) . Also it seems to lack a litle sharpness. But the subject is fine and the image is ok too.
