Don't be in a rush to sell your art. People will always be here to buy, so just spend time practicing. :3 I've been drawing for years and I'm still not sure if I'm ready to sell or take commissions.
I don't think you should be afraid to raise the prices a bit. I don't think I would buy this kind of art, but I'm sure that anyone who wants to buy it wouldn't mind paying 50-90 points for one of your full bodies, rather than only 30.
