Good composition. For a black and white, your tonal range needs to be pushed just a bit. More true white and richer black. This can be done through curves. I like your model's pose.
Nice clean shot. Would work a lot better if you could see the guy's face. He could be banging his fist against the wall in anger for all I can tell from this. Like the processing quite a bit.
This is a body language pose that I expected to see a lot of - and yet there hasn't been that much of it. I like the DPC site on the monitor - it is crucial to telling the story of "Triumph." Interesting that you chose to have the subject's back to the camera (vs. profile or forward).
Nice capture - Nice tones - Just find that very white table corner with nothing on it very distracting - maybe a winning lottery ticket on there or something?
Nice idea - brought a smile to my face. :) One of those quiet moments of triumph we don't share with others. Good composition, although I'd suggest taking the pictures off the wall - they interfere with your subject. Also, the shadows are a little too dark. If you use Photoshop, check out the selective color adjustment layer. Without making selections within the image, you can tweak how dark the blacks, whites, and neutrals are. You can also adjust colors, but I find it most useful for setting those.
