weight could be 0.7 - 1( makes it flexible ) - trained for 768 (can have better results)
to keep close to their old design try any of these - or put in Neg to reduce chance - SFW/NSFW
may need to add 3d, or realistic, in neg for certain 2d/anime styles due to having more 3d image training
was trained without a head - nothing gore related - this may be the most difficult LORA to work with unlike some of the other GW loras
face/body
studentofmisery, headless, headless female, or missing head, or head out of frame,
pale skin, ghost, - may help - or just inpaint something else over their head
some styles may spawn a head or replace it with an object in some cases
I suggest putting anything face/headwear related in NEG - face, head, eyes, nose, helmet, floating object, hat, hair, skeleton,
camera angles like from below, can help hide the head
Outfit
Anything school uniform related or gym clothes - below is a list of generic prompts -
black school uniform , miniskirt, red tie,
skirt, pleated skirt, black skirt, socks,
knee highs, sailor collar, shoes, white shirt,
neckerchief, black socks, long sleeves,

black shirt, red neckerchief,
