I sculpted one of these guys a year or so ago. Unfortunately I decided to spray paint it black, but didnt use a primer. It stayed all sticky and I had to discard it. Ive tried to make another one since then, but couldnt get it as good as that first. Last night I gave it one more go and got pretty close.
If you, or someone you know, can make a lot of these, get them in contact. Id love to sell these in a series.
