Definately a broken building that you captured, so you met the challenge well I'd say. The fence with the sign on it really doesn't add much in my opinion other than telling the viewer that the building isn't accessible for whatever reason and is possibly dangerous (you can't really read the sign).
The focus throughout the photo seems a bit off except maybe on the door where it seems good -- A smaller aperture here probably would have gotten a bit higher of a score.
Also, the top part of the building seems a bit noisy. If you used a faster ISO and a longer shuter speed, possibly the image would have come out a bit stronger. And like others have said, I think the white balance may have been a bit off.
Otherwise, great subject choice, just a few things that could have bumped up your score some for next time. Keep shooting!
