Use ADetailer for perfect eyes
This is a character pack model of 17 characters from Ishura
I trained in Civitai off of 351 images I gathered myself
The model does a good job in capturing the character looks and outfit
I recommend keeping the model at 1 strength, cfg scale: 4, and sampling steps: 36, also if you are generating Yawika images use colored skin in the negative prompt.
