Your dolls are beautiful- But to be honest, I think they look more like collector dolls than dolls to play with.
You should go to a site like Etsy, look at the doll-sellers, see what they are offering, and how much. You can also look at each individual seller's sales- not how much they sold for, but click on where it says 22 sales, or 50 sales, whatever the number is, and you can see what they've sold and how long they've been selling- that should help you at least some.
And quilting wins for me, hands down. I make dolls, too-
