A very cool subject. Focus and dof pretty good. The sky seems kind of washed out. I'm thinking that this subject matter has the potential for something more dynamic, especially for this challenge. Although this is fine compositionally, it does have the pov of just standing at the end of the row of bikes and taking the shot. This is the perspective that you would expect to see if walking by. Maybe something more dramatic from down low, or up high, something that one would not normally see, could improve the presentation of this shot.
