This is the most underrated photo in the challenge. Please don't let your low score discourage you from submitting such artistic and thought provoking work in the future.
I would have had the fence in focus instead of the person. Makes it look like you were going for a portrait but had bad lighting and annoying distractions. And what is the enemy? And why the latch key? But still an interesting picture that at least had me thinking.
I really like the framing and concept of this image, though I find that it's really greyed out and flat. To me, it would be much more interesting with more 'depth'.
