I'd have taken closer up to get the detail on some of the metal. Put it in focus, maybe, full color not sepia.
As the shot stands, I'd have tried to get out the whitespace on the top, feels unbalanced or strange with the white wall taking up so much. Since there's no focal point in the image, having the wall take up so much of the frame just doesn't seem to work so well.
I believe a close up showing detail on the piece could be interesting with the right lighting. Try it again, there's an awesome shot somewhere in this scene!
