XV,
First you'd need to know what you plan on doing with the end result, paint it or cast it.
If you plan on just sculpting it, then painting it, Super Sculpey's what would work best.
You can also cast it too...
If you plan on casting these, then any of the above is good, but you can't paint the raw
clay or wax, and casting is a whole 'nother deal to learn.
You didn't mention how you wanted to go about this, but if this is one of your firsts, then
definitely go with Super Sculpey, it's pretty forgiving, and holds detail fairly well, a LOT
of professional sculptors use it.
Don't forget too, you can bake it more than once, so to make sure that you do get more
detail into it, bake it so you can hold it.
You can add little parts to it and work on it a lot easier that way.
If you wanted, buy a heat gun, but definitely learn how long to hold it on one area.
If you leave it in a small area, it will brown before you know it, and I mean, it's FAST!
You'd need to practice some is what that means...
Also, with Super Sculpey you can take your time, and it's not bad stuff at all, and I would
imagine that you'd learn a lot by playing around with it.
Probably most of today's good sculptors started with it, so it can't be all bad.
Get good with using a certain medium, then graduate to something else, then maybe try
your hand at using wax, then casting.
Without knowing what you plan on doing with it, it's kind'a open as to what you need.
