Crop it
I like this image quite a bit. The reflections are interesting and pleasing. My only suggestion is to crop it so that you don't have 1/2 buildings or signs at the ends. I wish the sign were whole as the ability to read it would give the shot more character.
Of course, level it, that's a good thing.
Then my best advice is to shoot like crazy taking time to critique your photos and what you like and don't. That exercise will take you far.
Oh yeah, read, ... lots.
Michael Freeman's The Photographer's Eye is wonderful for composition basics and several things that most of us don't really think about.
