Anna,
I am going to stick my neck out here against everyone else. I like the night shot, the reflections are good but everything above the word "Ocean World" is in the dark. When taking these sort of shots try taking them half an hour or so after the sun has gone down. All the lights will be recorded but there will still be some colour in the sky which will also be recorded but you still achieve that low light look to your picture but still retain detail and dont have an inky black sky.
Hope this helps, give it a try
Soren.
