Fantastic contrast - fantastic composition! I like the pair of guys sitting on either side of the lamp post. And now that my attention is drawn to the lamps, I have to say that I wish they weren't cut off at the top. Very appealing shot!
This almost looks like a photo shoot where all the cast have been choreographed. the silhouettes are great and the tones of the water are spectacular, but what I think really makes the image is the person leaning against the lamppost with his arm rested on his leg. Great capture.
Good silloute (yeah yeah don't know how to spell it) .. like it but think you should have cropped few pixels of each side to take away the litle shaddows of the people that is not possible to see in the photo
