I pinjam-ed your hand a little bit.

Updated: Forgot to add the important shadow underneath the paper. LoL!

Anyway, here's a PSD file though the stuff I used to create such an effect was:

- Pen Tool.
- Gradient.
- Masking. (for your hand)

Cheers.

draw a triangle on a new layer, fill it with a colour and delete the selection on your background layer.
Then Free Transform it, right click on it and select "Warp".
