looking for more here, perspective change/lighting, seems like maybe you were trying to highlight the differences between the various wheel designs but not really clear enough to me, maybe should have shot from a lower height & closer in
Good. Because the background is so dark perhaps cropping to concentrate on the wheels would have been better. Or a front on view of the wheels to highlight the different spoke types.
I like this shot but it seems too dark IMO. Better if you could've taken the shot at a different time when there is more sunlight in the area. Good luck!
Bikes the topic I love the best. I do think the sunlight is killing your shot. Because of buildings, and the available light you might of tried shooting this at a different angle or a different time of day.
