HMM. This is a difficult one to comment on. The composition could of been different. I might of gotten more of the first set of bike racks, it looks like you were more focused on getting the shadows. It's an interesting picture, but lacking something in my opinion. I was actually reminded of a picture I have hanging in my bedroom when I saw this photo since it's somewhat similiar, only difference is that it has 2 older bikes leaning up against each other and the focus is on a boquiet of a dozen red roses that is strapped down on one of the bikes over the rear tire sort of thing... hard to picture for you I'm sure, but the bikes are leaned up against a railing, and I have a huge love for this picture. It reminds me of Holland, where I was born, since everybody bikes there and seems to be the main transportation for the population.
Anyways, long story short, it's about how you like it
I think the picture is as good as it is going to get as shown right now.
Thanks for sharing
