WOW, WOW, WOW... I really like the tones, the lighting, the texture, the shallow DOF, the implied masculinity. 10. Sorry I can not give it a higher vote.
something about this image makes my skin crawl haha. i might have had a hard time telling what it was if this wasn't the hands challenge. i like the dark streak moving from just above the wrist towards what i'm assuming is the blade (pinky side) of the hand. one improvement maybe would be to have reduced highlights on the lower wrist/forearm area to brin gout that dark trail more. it's the most captivating part of the image.
That's a great title. Makes me think of Mike on that show "Dirty Jobs." Really great light. I wish maybe a tad more were in focus, but I see the shallow depth you were going for.
