The composition of this works very well for me. Between the quality of the light and the angles, there are two completely removed yet joined pictures here - the city, and the people on the bridge. Excellent use of lines and angles.
I love the strong contrast and shadows. I wouldn't have even thought about the people walking away, but I read aguapreta's comments first. Must stop doing that.
Interesting, but not ass good as some of your other stuff. I like the framing and lighting, but not the fact that the people are walking away from the camera.
