|You must by now be fed up with all the "doesn't meet the challenge" comments, and presumably the associated poor scores. Especially as it's a pretty good photograph, and quite interesting from a compositional point of view. However, whether this light is on or off, the fact is that your image will not be seen as having any meaningful association with "darkness". Pity, because as I said, it's not a bad photograph at all. 5
P.S. Please don't take this personally. I'm also getting murdered in the voting, but for the opposite reason; TOO dark!
