This is something new, never done facial expressions before.

Trained only on realistic images. It works with characters, but depending on the character it's behaviour changes, some toon characters can't do that half raised lip thing at all, in some cases the teeth are large.

Without the lora, you would get fangs and animal like fatures with the tag "snarling" if it even reacts to it.

Trained on IL XL 1.1 Recommended Lora strength: 0.8 - 1

Recommended helper tag:

clenched teeth - (clenched teeth:0.8)

feel free to experiment with any teeth related tags, but I found this one the most reliable

I generated with Euler A Automatic, 25 steps, CFG 5.

Schedule type: automatic I use No embeddings, NO negatives and NO quality tags at all! Only the style and medium tags.

Recommended Resolutions: (SDXL standards) - Pony/IL too
