ok - first of all, sorry for my english!!
I took the mirror of our bathroom and layed it on the table. Then I took a big, black paper (din A2) and putted it a bit under the mirror and then from the backside up over the mirror, like a roof. This is necessary for getting a black background. Now I layed the snake on the mirror and shooted ;-). And... a little bit of corrections in photoshop. finish.
best regards
Mumi
