My take on Yukiko Amagi from Persona 4.

As always the dataset was manually curated from official artwork, in-game screenshots, and screencaps from the P4/P4G animes & Dancing All Night.

V3 removes the yellow tint that plagued the previous versions. Her casual outfits still aren't perfect: the cableknit pattern from her red sweaters bleeds into her casual winter dress, and I just don't know the appropriate way to describe the casual summer shirt to reproduce it consistently. But overall I still consider this an upgrade from V2, give it a go and let me know if you agree.
