Portrait Sculpting 3

After a while, the sculpture is done and I started making a mold of it.

I usually make a dividing wall using wed clay, but this time, I want to try another way. I'm thinking two parts silicone and plaster bandage shell.

I applied first layer of silicone on the sculpture to get details. I also start adding thickened  silicone to under cut.

I will apply second coat when silicone sets.
