The clouds in the background remind me of smoke from fireworks or some sort of explosive. With the barbed wire and dark silhouette of rigid geometric metal, I get a feeling of foreboding. Not sure if that was your intent, but I like it.
@darchibald that is an interesting interpretation and has connotations of war and imprisonment, and I can see what you are saying. Thank you for your interpretation! It was of course the edge of a pylon with the setting sun catching the clouds in the distance!
