That's pretty cool. I like the pattern of the barbed wire, and the idea of framing one side with the building but I'm not so sure about the lean it has from the perspective (shooting from what seems to be a lower vantage point). I'm not so sure I'd straighten it though, I kind of like the angle I think it just might have been balanced better if more of the building was showing instead of just the edge.
Nice subject for black and white; I shoot film too and like doing B&W.
