The modeling on this project is being done in Castilene, which is fantastic medium and, happily, working just liked I hoped it would in combination with the urethane foam. The downside of Castilene is that it's slow, like plasticene, and the surface is finicky. The problem is that, or me, a finicky surface is like the tar baby - I can get stuck to trying to perfect the surface, when I really need to be working the form.
With that in mind, I am very deliberately trying to keep away from working the surface. In this clip you can see I'm working with a wax pen and an alcohol torch, trying to keep the Castilene soft and the modeling light.
The deadlines on this project are tight enough that I'm actually thinking about my "touch rate" - trying make sure that I'm moving quickly and working the piece as a whole without getting stuck resolving individual elements or problem areas.
