>>57254931V4 is pretty consistent with Tuuli from Ascendance of a Bookworm, who only has 19 Danbooru hits. Gotta specify her hair and eyes, but that should be a given anyway. She's not quite as bang-on accurate when drawn alongside Chloe, but she's fine on her own. I do find the number required for consistent results depends on how many solo works they have, being lower if they have a few, whereas if all the art on there also includes other characters then it struggles.
