I wanted to do a good SDXL Lora so it is trained with realistic images. Illustrious is actually able to create this, but maybe the lora will help.

Please keep in mind to work with this lora responsible. All characters in the images are at full age and are doing this with consent.

Idea is to make the expression more extreme with frowning. Keep in mind they person can't scream and clench the teeth at the same time. youn need to choose. Also Closing eyes doesn't work when you describe the eye color.

Version 2.0 Illustrious

cranked up the training pics from 40 to 240 pics.

It will give the expression more details but will make it more realistic.

It depends a bit on the art style.

To enhance: painful expression, in pain, terrified, frowning, scared, crying, screaming, closed eyes, wide terrified eyes, clenched teeth,
