Hi Anis,

I don't have the contruction curves anymore, but here's the method I used for the hands.
I hope it's clear enough.



Thanks for your comments, I'm happy you like it :)

@Danny,

I don't have any clue about how lit a scene myself, so I suppose it's far to be a good case study for you.
For this scene I've used 2 planes, one in the back (the white background you see is actually a light), and one on the left.
The overall background/environment is full white (at 25% of light emission). And I add an hdr for the reflection, to have some extra specular spot on the snowman.
