Very nice, I like the darkness. The chain gives it a tough edge, yet the man behind the microphone seems awefully calm.

This photo is dark, but it's not really saying "nighttime" to me. And it's a little unclear what he's doing... Maybe playing piano? Possibly just looking at his feet? Not being able to see what's going on is a little unsatisfying. Also, there's definitely some blur going on here that is distracting.
