This is a look at the ugly process of making headsculpts.
This is from the Anakin 1/4 scale statue from Sideshow. you can see the finished sculpt here, from the deviation I put up before. [link]
each row of photos kind of shows a slight progression. This is one of the only sculpts I took the time to snap a few "in-progress" photos of. I had hoped it would become a habit,
but as usual I slipped out of the groove.
As for insight into the process, you really just start carving away at the wax, adding back melted blobs to start building up your forms. Eventually as you start to get things on the right track, you sand them smoother with heated sanding sponges.
