I like this a lot. My only suggestion would be to try BW - the cyan color of the spots on the right side is a little distracting. The spots and also the rust would stand out from the surface because they are darker, and of course you could darken the spots further during conversion if you wanted.
I like this quite a bit and wouldn't change a thing... other than the title, which robs us of the fun of seeing this piece without clues as to what it is
