Excellent composition! I'm not a big fan of nightscapes in B&W, but I quite like this one. One thing I'm not keen on is the lamp post as it's just a distraction. Theres also a blotch of light in the centre of the image that you could try and clone out and see if you can reduce the noise a tad bit using the 'reduce noise' filter in PS.
I'd quite like to see the colour version of this image though.......
