It is actually two hands :) And it is possible to hold the hands like that :P 

excuse me for being rude, but that really looks like a badly screwed up hand. i am trying hard to figure where is the hand at all, or how how is it placed to make the gesture :V

Thanks all :) 

Denmen707 - Yeah, see your point, if I have some sparetime tomorrow or in the weekend, I'll see if I can make it a little more exciting.

shibumi - If I have time to do it I'll make some more contrast on the thumbnail :) About the pointing finger, it is actually ment to bend, because the right hand thumb is holding around the tip of it.

Great idea. I like the way you handled the composition given that you're working in a relatively small space. I think the thumbnail could use a little more contrast to define it a bit more. Also, the pointing finger of the left hand doesn't look quite right.  I think it maybe needs to be a little longer and it looks like it's bending slightly backwards at it's joint.

Great concept for the challenge, nice shading on the hands too.

really nice, you could haave done something more with the actual shadow through
