At first thought you think: "The barb wire lines screw this up." But at second thought it gives a feeling of "nobody enters here", enhancing the empty house. Unfortunate that the sky is a bit blah, it could have given this more impact.
Good subject, and the colors give a real feeling of desolation. I've got mixed feelings about the wires. Barbed wire certainly gives a "country" feel, but I'm not sure it adds that much across the middle of this picture.
