Argh, now I have the song "You belong to the city, you belong to the night" going through my head! You've captured the beauty and lovely colors of the city at night - love the sparkle and the lights of the city and the reflections in the water below.
I was getting ready to say exactly what germaine said. The colors and reflections are fantastic. There's an odd little red light in the sky off to the right of one of the buildings. It almost looks like lens flare, which I wouldn't have expected with this shot.
