I wanted to do a character model of my home girl Iori, specifically her from the 2011 anime. There is already an excellent Iori model (https://civitai.com/models/359890, thanks Nag_!), but it is in the style of The Idolmaster Million Live!
Main keywords you'll want to use:
Iori Minase, brown hair, brown eyes, long hair,
Some suggested outfits:
Pink dress, short sleeves, black hairband
Baseball uniform, striped, belt, hat, short sleeves
Water gun, shirt, hairband
Witch hat, jewlery, necklace, cape, wand
Mermaid, underwater, shell bikini, hairband, shell, fish
Space suit, helmet
