These make really great subjects for photos. This one is a little dark though. Being very reflective is also good because you can show other stuff that might tie into your photo directly, or not.
Very nice composition and I like the contrasts you've captured without blowing out any of the highlights. I would have liked to have seen a little more of the texture of the metal though. Also, if those are dust specks in the shadow areas you could have blown them out.
