A beautiful hand.
Since this is posted in the critique gallery:
May be the hand is a little bit to light compared to the rest of the body?
What about a distant reflector to lighten up the rest of the body a bit?
I really love the shapes you have created with the blacks and whites which go beyond the rendering of a human form, which is hard to explain exactly as somehow it approaches the abstract.
Before of all thanks for comments.
I tried to make a quite abstract image as, arigram wrote; anyway I'll see, during printing, if a different balance of lights between the hand and the body will be better or not.
