Hmm, I don't think it's bad at all. It looks like the voters didn't love it or hate it (as evidenced by the ton of 5 votes). Technically it is quite sound. Good lighting, nice background (although it looks noisy, I guess from the ISO 1000), and sharp subject. In the end, I think it has only limited potential as an abstract. We grasp it quickly and move on. It is neither mysterious (we know what it is), nor does it captivate with pattern or design (it's too simple). This is probably what limited your score in the end.
