You have to buy the head texture, Like the one i have on right now is made buy me.... I had to buy a 20k head texuture (in your case you would get a lower resolution for 2k) and then you would upload a picture to that head texture, so right now you have betted the money that you have, not all, but your like almost 1k short of actually using the head ingame, all you would have is the flat...

Oh and would you like to bet somemore? if so I can raise it a little
