Very well executed. The way you've composed the shot pulls in the viewer and demands one to keep looking at those very masculine arms. Love the post processing treatment as well. Kind of a nitty girtty metalic feel. Very cool.
I give high marks for idea and execution, for tone still present in a high key shot, and for conveying a great idea so well; working within the square crop and leaving so much to the imagination.
Now, two very small critiques; these arms need something, more dirt, water sprayed on them, a shirt? something because they are not as convincing as the rest. Also, the chain; it might be better thicker and rusty.
Two very small things that don't really distract froma great shot;
Great job. The lighting is stupendous. The leading line from the chain, the obvious fact that he is actually pulling the chain...they all just come together for a great photo.
Effective work but really bad to have background so dark and whit out a rating in black r=0 g=0 b=0 better to not go so far to black side, if you have a black background better to have it right
Good idea, the composition is fitting. Lighting set up is good with the sudden disruptions between light and shadow. Maybe a little harsh in some places, but otherwise good.
