Fair points above about keystoning and convergence. Also as said, in this case the building is awkwardly cut off. Not that you should have to include all of a building in a picture, that could be silly, but you do need a sense of composition (framing), irrespective of converging verticals or horizontals.
The funny thing about composition is that you can read about principles and 'rules', but essentially it depends on intuition - a feel for what works and what doesn't. I think this means that it can't readily be taught. It can possibly be acquired (or improved) by studying existing photographs, but overall it's about developing a sensitivity rather than a technique.
Also it's not just to do with shapes within the frame - tonality and focus may also be contributors to a sense of depth and how the picture interacts with the frame that bounds it.
Steve, I've just examined your Flickr and there are some great original and fun shots there, but you are very inconsistent. It's as if you need an editor (or mentor) for what to dump and what to keep. But that person can be you. Keep at it.
