Face of demon girl: horns, pointy ears, black lips, black sclera, blue eyes, slit pupils.
Сan also specify other parts of the prompt: glowing eyes, blue sclera, no pupils.
I trained LoRA on pictures with blue skin, but it seems to work with other colors (red, black, etc.).

The same goes for eyes, I trained it on pictures with blue eyes, but it can also draw other eye colors, just set the color weight in the prompt.

To make the result acceptable:

1. Image generation

2. Hi-res fix

3. Upscale (x1.5)

4. Face-fix

This is the second lora in my entire experience, I think it doesn’t work well, but you can test :)
