Generally, horizontal or vertical lines aren't as interesting as diagonals (as others regularly remind me). I also think that brightening this a lot would help. I realize this was minimal editing, but for future efforts, try adding more light or lengthening the exposure time.
Honestly for a minimal editing, I think this is a terrific shot. I see some much potential here, and post would really bring it out. This one should have scored a bit higher. My only suggestion would to have the needles coming toward the viewer in focus. Great shot.
