Very nice shot. I like the warmth of this photo. I imagine sitting on the deck of a boat relaxing with a drink and a nice cigar just enjoying the view. There seems to be quite a bit of grain in the sky, most likely due to high ISO and/or long exposure time. I don't know if it detracts from the photo, but it is there and noticeable.
My immediate thought is that you've missed the opportunity for a really good composition here - those three buildings with collonades are perfectly placed relative to one another for a very striking picture - but who knows whether you had the zoom etc. to do that? This seems confused - in sense of period, composition (the gridge and bright lights way off image right - and negative space above and below - makes the sky and foreground almmost seem like a border top and bottom, but it's just black, pretty much.
Wow Factor 10. I love this!!! It's so clear and sharp. Well-done night shots always appeal to me in that "10" way. Good luck! (but you probably don't need it :)
