>>6284409>>6284415Currently I've thought of two easier ways to make facial expressions without drilling and cutting resin.
1. Build up the face area with epoxy putty, making the open mouth area in reverse, then sand down the edges back into the face, etc.
2. Grind/putty down the area nice and flat and make the mouth area blank, like them figma blank faces and use flat decals/paint in the mouth expression, pic related.
Whichever way I might try it, doubtful I can get that "Stylet puffs her face all angry like" from the manga.
