PROBLEM: It surely already happened to you: you draw a new head. Fully on your own. So you work long on it.
Finnaly its ready and you upload it and press yes.
Then you see a problem: the head is not on the right place! Surely you are pissed.

SOLUTION:How to avoid that?: A private room, (that is not reachable for the world) where you get into if you want to try the head out. (notice: you didn't buy it then) if you're ok you can buy it. If not, you leave the room without your head.

This will avoid much ugly, wrong placed heads.

Greetings, MLG.
