New Boy Head- Wip

Hi Friends,
here's a photo of the new head Wip. He is quite large and I need him to shrink after the finish somehow.
Exactly how I'll do it, I know not been. Probably several junk porcelain molds and castings. It is expensive ...
However, I have heard of a material which allows to zoom in and/or shrink models.
Does' probably only be bought in the United States. :-/
Bye for now and take care!
