I bought a few cubes of Sculpey III a couple weeks ago when it happened to be on sale and yesterday I finally tried fooling around with it. I've never made any kind of model before so this was definitely a learning experience. I was trying to emulate my drawing style to make a 3d version of one of my characters and I'm pretty pleased with the results. There is a piece of wood dowel inside the neck to support the weight of the head. I think on my next go I will pick up some super sculpey and some actual modeling tools though, as I did this one with nothing but an exacto knife and a mechanical pencil. You can tell I left it in the oven a bit too long because it burned a little bit, but I'm going to try painting it so hopefully that will cover up those imperfections!
Here's a page from my sketchbook to compare my drawing style. I was basing this off the blue haired guy on the right mostly.
Here's the painted version!
