Hey Brian, while searching Google for "Killer Klown sculpts" I came across this thread.
As a beginner in miniature sculpting, your WIP photos inspired me.
Miniatures don't take a lot of time, so I knocked this out in a few hours this weekend.
The core of the head is a thin floral stem wire wrapped in compressed aluminum foil. For the ears I used a small piece of a disposable aluminum baking tin and carefully added a very thin layer of Super Sculpey.
I have since smoothed out the lines with mineral oil, baked it to harden, added teeth, and baked again. He still needs eyes. I don't intend on painting him, but maybe down the road.
