You take great bike shots, I've seen a few from you now and they're awesome - so moody. And the frame does work quite well. Makes me think of a film still.
The borders works so well for me, re your many candid shots, and this one is no exception.
I love your style, and love the simplicity of how the bicycles are all in a row..... A great street candid shot here.....
I love pictures of bicycles! What's interesting to me in this one are the green lines on the sidewalk - they match the color of the back bike. And I like the legs at the top of the frame, both at the end of the sidewalk and in the crosswalk - nice pattern kinda thing going on there.
