I had a little self portrait session I setup downstairs in my basement with one speedlight on a stand a awesome stone wall as the background. I was going for some moody shots I just happened to do this, as I'm just messing around, and I thought it came out very well, almost has like a movie type feel to it. Probably one of my favorite ones.
This photo could be portrayed as many things, a criminal, a mobster, hell, maybe even a rock star or just a total bad ass. The decision is up to you.
