Thought I'd give you a small update, as people are asking about it and it makes more sense to answer in one go.
Yes, it's the same head sculpt, except not painted. It's cast in resin again, white resin this time, because I've decided to just sculpt the hair as well. I'm still keeping the head that's already painted and has a wig, but I'm doing this one with sculpted hair.
The body is pretty much done, though ideally I'd like to do another mold of it. But as this stuff is rather expensive, it'll have to wait. Which is annoying because I can't wait to finally have it finished!
