C&C per req:
1. Nice shot, good 'cool' pose & expression. I'm not much fussed about the 'vignette' effect upper left, and the image does need leveling. I wish you'd used a reflector or fill-flash to put a little light into his eyes, and NOT your on-camera speedlight. Remember, the hot shoe on your camera is ONLY there to support a remote trigger!
2. I see where you were going here, but IMO, it didn't work. The sky is totally blown and featureless, his face is grossly underexposed, and his arms & legs? They look jaundiced! This is another image where a single OCF would have saved the day. Even a big reflector would have helped. A LOT!
3. I don't get the placement of his face in the image, and while it's not the end of the world to crop the top of someone's head, but the crop on the chin really hurts the image IMO.
4. Based on the angle of his head, I would prefer him to have been placed on the LH side of the image, and I think this one, with a bit more road in the image, and a LOT less DoF would have been a great shot for monochrome.
Overall, they're not a bad set by any means. The ideas are good, but the overall execution suffers due to a lack of technical expertise.
Just my $00.02 worth - your mileage may vary.
