I'm doing a wind-up doll for Halloween this year. But what kind of help are you looking for? It looks like you have a lot of the same inspiration pics that I do on my pinterest (link in my sig).
It's an easy costume to do homemade, just see what's in your closet and what you can start building around, whether it's more of an old-fashioned porcelain doll in a gauzy dress, or a ragdoll in a pinafore, or a babydoll in a nightgown, etc. I already had a leotard, tights, and ballet shoes to structure my costume around, so that's why I'm going with a busted ballerina wind-up doll. I just found an easy tutu tute, grabbed some tulle from eBay, and went nuts.
I looked at all the different makeup tutorials and tried a few things to decide what would look best with my face.
So while my eyes and cheeks are more like this --

My lips are too much for the really artificial heart shape (it looks weird and unflattering), so I'm just going to do a pink lip, but here's a doll lip tute --

And it looks like you already have several broken-porcelain makeup ideas pinned.
You've got the basis, just sit down and look at your wardrobe, decide how much you want to spend vs how much it might cost to DIY, grab some drugstore makeup to help with the broken porcelain face, and you're good to go!
ETA: false lashes are definitely your friend for the doll face look, don't skimp on them!
