I liked that I had to let my eyes focus a minute to figure out the guy with the glasses and the hat. That bright bit of light to the upper left is a touch of a distraction but I like the idea of the shot.
OK, I'm going through the Free Study submissions, purposefully finding those images I think are shot with a less conventional eye - this is one of those images! Thanks for offering something that isn't just DPC friendly eye-candy (though of course there's nothing wrong with eye-candy):
Positives: Just a flat-out superb composition. The juxtaposition of the hyper-sharp mic and the guy in the background, separate but linked and coherent is quite excellent. I like the lighting and colours too - bright but still communicative of an enclosed space. You have demonstrated a great eye for a photo here.
Critical stuff: I do think the crop of the chin is slightly problematic but not disastrously so. Thinking about some of the software I have, I imagine using Viveza with a control point on the guy's cheek and taking down the luminosity of that whole area and lifting the contrast a little. Just choices though and it would certainly offer a less authentic image. I think such an approach might have address the slightly flat lighting though.
