I'm getting my feet wet in on small mammals using dry preservation and carved foam/wrapped bodies. I find that it's hard to model a nice full shape, especially the eyes, but still be able to pull on the head skin without squishing the clay. I'm also still learning through experience how much shrink to anticipate. When I don't use quite enough clay, I get a slightly sunken, haggard look as things begin to dry. Is there a way to cheat by adding a bit of fullness at this point? I considered injecting caulk to plump things up a bit around the ankles, cheeks, etc. But searching shows that people really only use caulk for bird wings and feet, which makes me think it must be a terrible idea to use for mammal plumping. Any tips and feedback appreciated!
