yeah, sorry about that, maybe take the bevel off - add a bit of a frame around the edge if you wish, but the bevel isn't very nice, might be worth playing with the contrast on it, as the building and the sky tend to be the same shade.
As for the composition, I think there are possibly two shots in there, the building through the barb wire and the flag through the barb wire, try doing a crop just above the roofline for one, and include it in for the other, as there is a long way up from the buildng to the flag.
Keep yer head down mate.
