Best of the "Hey you..." photo's in this challenge IMO. Very nice job in the composition in placing your subject within the frame. Also like the way you restrained yourself from cropping this to try and "fill the frame" with the primary subject. The space around the man (feeling of emptiness, coldness, large void) is what helps make this image work. Well done! Good luck in the challenge.
Simple. Nice use of negative space. Limited detail works well too. One of the few occasions where the utterly blank white sky is better than a sky with some detail or colour!
Good job getting a totally white background. There does seem to be some noise on teh guy's shirt, and some glow low on the horizon (from sharpening?) but overall pretty good.
