I have to agree with mdcrisp on this one. I feel the building in the background is competing and not supporting the bus which I believe is what you wanted the object of the shot to be correct?
I like the deep blue of the building, it does seem to be competing with the bus though. I wonder if it would have looked better to blur out the bus with a long exposure and let the building become the subject. It's a bit disorienting to me with the subject out of focus.
