shame about the shadows behind the wire, from the angle it has been taken I think it couldnt be croped square, I think it would have had a better effect if you had put it on the slant, good luck
You actually have a lot going on here. Pattern from the metal, pattern in the shadow, pattern of the wood grain. The title infers that the metal is your subject. My eyes are only drawn to the metal in the lower center area. Was this a rounded subject?
