I much prefer the Super Sculpey. Its much easier to work with as its not as sticky and doesnt require constant damping of my tools. I also like the fact that it gives a near infinte working time compaired to the epoxy (usually only an hour or so before it becomes too hard to shape). Its a bit harder to sand to the same smooth finish but, overall I find it a better material.
I've been working with epoxy for a couple months now and its very useful if but a bit quirky. While I'm still getting used to it, having used it in conjunction with normal sculpey does wonders to how I can reliably pose the sculpture without having it break. Its very cool.
I'm glad you're liking Super Sculpey, I always recommend it for beginners due to its ease of use but I've seen professionals use it as well. I really like the stuff.
Ah so there was no armature for the wings. Six inches sounds like a good size to sculpt this is in. Not too big and not so small that making detail gets to be a pain. Look forward to seeing the final painted version.
There isnt an armature persay for the wings but there is a sheet of plasticard running throught the middle to act as support. I used a simplified version of my usual wing method (tutorial: [link] )for this piece due to differeing materials
