The Lora should work well with the DucHaiten-Pony-XL (no-score)checkpoint.
When initially generating the images i also used, Detail Tweaker XL, インナーヘアーカラー/Inner Color.

I hope you have fun generating and that everything works as intended.
Ideally you use the Lora at 0,6 strength.

The Lora should be trained for Sfw and NSFW.
(Be careful to not add something that makes her appear even younger.)
