weight 0.9 is best.

This model is based on the SDXL Pony Model.

I created this LoRA as requested.

character appearance
aachisato, black hair, short twintails, low twintails, swept bangs, hair ornament, hairclip, brown eyes, medium breasts

I was very short on dataset images to create this LoRA.
There are no specific outfit recommendations, as it is trained on images of the character's face.
You can dress character in any outfit.

In the sample images, used hires.fix and the extension Adetailer.
