This is my first LoRA it's a work in progress still. It is trained on AutismMixSDXL.
The training tag is LoFi_Girl_Pony and the weight is around 0.5-0.8.
Reason being, that higher levers mess up fingers.
Use the ADetailer with Face.
Also, although not necessary you could also add the following tags to help it,
ponytail, brown hair, headphones, green sweater, red scarf,
PS: It works really well with High Hires. fix with the following setting
For steps use about half of your generation steps I use 35 Steps so for Hires. fix it will be 17 for me.
Here are the exact setting:
Hires upscale: 2, Hires steps: 17, Hires upscaler: R-ESRGAN 4x+ Anime6B
