weight 0.9 is best.

This model is based on the SDXL Pony Model.
It doesn't work with Animagine XL Checkpoint.

I created this LoRA as requested.

outfit1
aasnake, long hair, white hair, dark skin, earrings, yellow eyes, symbol-shaped pupils, black wings, small breasts. sundress, white dress, sleeveless, armlet
+ knee boots, black footwear

I uploaded a sample image of the outfit as a post.

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

If you want more detail in character's eyes pupils, i recommend using the extension Adetailer unconditionally.
