I like the idea and the composition (position of the pump and lighter part of the sky, the framing of the tress and lack of power lines). If there was more 'city' in it, it would improve it a lot, but that might require a different location or city. Or you could wait another 20 minutes and take a second shot for the city in twilight. I'm not sure how much it would help with the particular city here though.
A little bit of haloing on the left by the building which itself doesn't add much (looks like you tried to lighten it), but I'm not sure a 'complete newb' needs to worry too much about those details.
I'd like to see more of your shots like this (I looked at your Flickr, but it's completely different). Are you planning on shooting more landscape-type shots?
