Do they actually have a free version these days or is it still Sculptris? I remember being so mad when they grabbed that and then did nothing at all with it forever.

I've found 3d improved all my skills in the things you're hoping to improve so I hope that works out for you too :)

Though I hope you actually also keep improving at drawing as that completely eluded me, I cheat there and draw over my bases coz my 3d is a lot better than my 2d XD
