Okay, first I had to say I had NO IDEA what you were talking about. The first thing that came to mind was hair loss because of the type of hair in the hand and the way it's arranged.
Then I read some of the comments and thought, "I never heard it that way!" :)
So, now that I know what you are going for...........
The lighting and tone set in this shot is very well done and expresses the setting that you were going for very nicely. But honestly the shoulder in the lower left corner? Very distracting and at first glance I couldn't tell what it was, shoulder, breast......? But bringing the shoulder back so it's not taking up so much of the shot might help quite a bit. I realize we risk showing something else when we do that but if you change the angle of the shot just a touch you could still get the message across while improving the overall composition of the shot. I tried just cropping it out but that leaves the shot very unbalanced.
Also the direction of the hand, it the fingers were pointing more towards the corner, offering a line through the shot it, again might help with the overall feel of the shot.
Now, the "hair". As mentioned previously, it just doesn't look realistic. You could have gone with some glue and some short hair or even string set up to make it look more like your leg or arm hair and this would have really sent the message across without any question.
Again, very nice tones and the setting is clear as a bell. I hope my comments help and Good Luck in Future Challenges.
Okay, I JUST figured this out, after ages of confusion. I think because it doesn't look like it's growing, it looks like you'd been pulling your hair out trying to come up with an idea? ;) What might have worked better would be some clear doublesided tape with short, furrier hair on it? (to look more like your leg, for example)
I have NO idea what this is portraying. string in a naked mans hand? huh? I could make the stretch to "if you keep touching it youll get hairy hands" but you may have wanted to use real hair if thats what you were going for.
