first of all let me say that I like this shot very much. Rusty things appeal to me in general. that said the out of focus area on the right distracts me from totally enjoying the image. I suppose you meant to show the depth of field thing eveyone so loves but it just doesn't seem necessary here for the composition of the shot.
I do like the subject choice, the lighting, the color and generally your handling of it. I think it would have been a better verticle shot with more space at the bottom to give it balance. Just my old eyes opinion.
