Sculpey is grey and leaves a powdery residue on your hands when you work with it. Super-Sculpey, the stuff I used on the Barada head, is flesh colored and much cleaner to work with. I don't know the real differences other than Super-Sculpey is more expensive.
Thanks for the compliment on the failed head, I was really happy with how he came out. Too bad I'll have to start over from scratch.
