This model should allow you to create characters and people with puckered lips. Currently only trained on realistic women, but with some weight tweaks and appropriate prompts it can be applied to other styles and characters.

I adjusted the captioning on the training data to hopefully avoid some problems with the 1.5 version of the Lora, but I'm still playing around with it. I've found that adding a phrase like "sticking out tongue" in the negative prompts can help fix some weird issues around the mouth.

Will look into expanding the training data to be more diverse and allow it to work with other styles in the future.
