I love how simple yet effective this shot is. You have not tried to get to much detail and yet the photo has enought in it to hold the viewers intrest. I always struggle with night shots as i end up trying to get to much in them and the look blurred so maybe next time i should copy your example .
its hard to think how you could improve this shot but if i have to be critical i would say 1) to many people are doing night bridge shots now and althought this is a great one its nothing original
also perhaps you needed to shoot from a slightly higher angle so the picture does not start with such a large clump of black bridge. also the lights under the buildings are distracting as there to light maybe you could of blurred them a little or lowed the saturation so they dont distact the viewer quite so much. but all in all its a great photo and thats why its got so many views
