Try using a tripod and not openign your shutter so long. this is a bit over-blown adn there isn't a single object in the image that has a sharp focus - essential for a shot like this.
Nice composition and I like the lights reflecting in the water. There appears to be some fog, but I still think the picture could use a tad more clarity.
Nice try at capturing a difficult shot. First thing is that the image is very soft, almost like there was condensation on the lens. Maybe it had been somewhere warm and bringing it out into the cold caused that. Secondly the composition could have been stronger without the wall in the foreground as it is a little distracting. Interested to find out where the bridge is, looks very European - Budapest?
overexposed ,nice location I would reshoot just for learning sake. ( I over/under expose many of mine too heck I could kill a 1gig card and maybe get 1 keeper.
