I really like this. It's one of those that just makes me go "man, how did you do that?" I like that the background is so dark, it really makes the light stand out.
Again with the title... Not to be over picky, but I can see both ends of the light. A tighter crop, or doing this shot over again so the ends blended in would be more pleasing to the eye. I do, however, quite like this shot and the thought behind it.
