His choice of t-shirt that matches the game they're playing makes me think either this is set up or he is far too devoted to chess, lol. Nice shot though, just wish the smoke wasn't there in his face, it barely obstructs but enough to bug me.
I like the contrasting look of the two players and the angle you chosed, using the hues of the background to further separate the subjects and isolating one from each other (or maybe I am making it all up and you never meant it that way, but that's how it looks to me). I find the sharpening a tad too strong, but it might be my monitor. Very good capture, congratulations.
