I hope you don't mind (I will take it down if you like) but I cropped your photo to see what it would look like without the lopped off building, and all the foreground.
It doesn't look too interesting, which is probably part of the point I am trying to get over.
Is your focus on the couple? or the building? In your photo the couple are the thing the eye is drawn to, as compositionally, they are pretty much hitting the rule of thirds. If the couple are the focus, I think you could have switched your camera angle, or position to make for a better shot.
If the building is your focus, then make sure you don't miss a bit of it, as it spoils the impact it would have if it was intact.
I hope this doesn't come over wrong, the internet doesn't always translate things the way I mean them. Sometimes one photograph can teach you how to become a much better photographer - I learnt the most from one I took a few months back, and Jiminy Clickitt showed me what was wrong with it - mainly a lack of focus on what was I actually taking a photograph of. I think from that point, I have thought much more about the focus of what I wanted in my picture, and it has helped me to improve. So please just take this as a friendly comment
