LORA to help bring more kawaii-ness out of your waifus. In my experience, just like the eyes, getting genuine anime pouts is hard for the AI to get right, or at least in a way that makes it look neat. With this LORA, you should be able to generate pouting characters with relative ease. In addition, you can also add squiggle clouds (denotes annoyance) and anger veins to further emphasize the pout, and even put them in speech bubbles.
Add this to the negatives, or you'll get several symbols around the character:
(multiple speech bubbles, multiple squiggles, more than 1 squiggle, multiple anger vein, more than 1 anger vein:1.4)
