Taken with a Nikon D3s and Nikkor 85mm f/1.8 lens.

WB set to tungsten
One SB-900 to fill in the wall slightly
One SB-900 in a Joe McNally soft box to camera left.

If I was to do it again I would put another flash to camera left to give some more seperation between his arm and the background, because right now the baggy sweat shirt begins to be lost in the background at about his elbow.
