i'd love to know your workflow on sculpey too Mark. not easy to bake one this size. i have ofetn wondered if you do a proportion of your figures in epoxy and then layer the sculpey on after so you can work without concerning yourself about very thick areas of sculpey.?
I do sculpt a core shape on the wire armature with super sculpey bulking it out. leaving areas at the joints open for pose adjusting. I then bake it. Then I sculpt over that with SS for a firmer armature form.
