When I tested it some different checkpoint and LORA's it seemed to work well with this LORA.
LORA weight 0.7 works great, but feel free to adjust the strength to your liking.
The settings for the Pony version can differ from the 1.5 version
Prompts that I usually used:
short hair, pink hair, black fur collar, angel wings, large wings, red outfit, detached sleeves, strapless, yellow eyes, red gem on forehead, black thighhighs
