Love the curves in the picture. What I like the best is that its a motion picture that you can actually make out. Staring closely at the buildings on the left you, can even make out the windows. And of course the black and white color give the picture much drama. I like it!
If you had played a bit with curves and had pushed it to the 'lightening' corner, you would have gotten a perfect abstract motion. Try it and you'll be surprised. If you want me to show it, send me an pm with your email. It would have really improved your image.
