I second blowing on the casting. It seems to magically make the bubbles rise to the surface and pop. 
Ditto on the other suggestions, and here's another - try using just paint for the mold release. Paint the casting then make the pour. Now if it does NOT work, you didn't hear it from me. But I have heard this technique espoused before, that the resin will stick to the paint and the paint will release it from the mold. Not sure how it'll work with a sculpey mold, but maybe better on an RTV mold or silicon mold. It could be worth experimenting with after you get a set of castings you're happy with.

I may not be a rivet counter, but I sure do like rivets!
