I quite like #2. Great mood and interesting composition, compared to #3 which is quite a bit more static and too much black for my taste. #1 is a dynamic image, particularly the repeating vertical yellow lines created by the light poles, however, I personally don't care for photos of night streets with light trails because it's so overdone. For a noob, I think you did quite well with it though.
Thanks very much. I should of posted the details with them too.
