I currently have an unused clear Obitsu 27cm body, and I'm planning on getting a head to be GLaDOS from the game Portal. Currently I'm working on a mockup using some actual head images, but I thought I'd ask for feedback on the design. I don't think there are any stern/frowning looking 27cm doll heads, so I was wondering if there would be any way to mod the lips on an Obitsu head. I've seen resin modded, but not vinyl other than cutting out eyeholes. In regards to eyeholes, is it easier to sculpt lids closed or carve them open? My default is just getting an eyeless head and drawing the eyes on, but there aren't many options of heads for that. Help? (I'll post the updated mockup when I finish it)
EDIT: Here's the mockup! Her hair is supposed to be white but I forgot to make the background transparent.
