Trained on 11 images. I used her military costume and bunny suit as training images. I use "(30yrs old:1.3)" prompt to make her look older.
Works well with Hassaku, MeinaPastel v4, Dark Sushi Mix 大颗寿司Mix, Mistoon_Anime v2.0 (kl-f8-anime2 VAE), Dark Sushi 2.5D 大颗寿司2.5D.
Koji v2.1 is good too, she might generate "younger", that's upon you and your preferences. You may test other models as well.
