It is strange now, even only a day later, to look at what's been accomplished in these many months, now that finally you seem to have taken a step forward. It all seemed so impossible, and it all looks so simple now.
Below are the pictures from a quick Eyelid Mould Test. The result is not perfect, but this may also be simply due to an imperfect sculpture, as it was quickly prepared for a quick test. What is important is that the steel ball fit snugly into the mould, and there was hardly any bleed in the silicone skin.
As suspected, the plaster is far too fragile for some of the fine details in the face.
One nostril hole broke off, and part of the parting of the mouth.
Final moulds will certainly need to be in a stronger material.
