I added a model.yaml wildcard as a base file to handle all ethnicities. This add much more combinations, since for example a single hairstyle is not tied anymore to a nationality. This second file list innate nationalities, eye colors, skin tone, hair texture/color/style/length, body build.
PLEASE open the corn-flakes-model.yaml file to comment options/values which does not suits your tastes.
This is a dynamic wildcard intended to bring you a lot of variations on generation.
In addition to the normal usage, you can use this yaml wildcard with the following text :
__cf-school-student/prompt-costume__ : prompt only the school uniform costume
__cf-school-student/prompt-full__ : prompt the costume with woman and location
