VERY well put! I seriously love categorizing and subcategorizing (and micro-categroizing lol...) all the different looks. Elfin < babydoll for sure. Kinda makes me want to start a thread with a detailed breakdown of them all
I can't really see her as a babydoll. Babydolls resemble porcelain dolls with round faces, button noses and alien but innocent features. Nastya is stunning and angelic and ethereal for sure, but she looks a lot more like one of the "catlike" or "elfin" girls to me. She may look innocent because, well, she is still 17. But I can definitely see her looks maturing (same as Sasha Luss) in a few years.
