Honestly, selling customs is hard. You can make a gorgeous doll, price it fairly, and nobody will touch it for ages... Meanwhile, they'll buy another doll that isn't so great, and you sit and wonder "Whyyyy?"
But they DO sell, it just takes time and patience... I'd say if you're going to sell them, do it through Etsy. 20 cents for a three month listing isn't too big a loss.
As for photography... I dunno, I think flaws show up better on film... Granted, you're a photographer, you know how to make things look nice. xD
But I saw the unedited pic of sleeping Cleo from the other thread, and she looked really nice. Pretty photos should be used to your advantage, nobody is going to be disappointed. xD ...And if you're worried about disappointing, then start the prices on the low end.
I think I'd price/buy the sleeping Cleo at around $40, though, for the doll nude.
