Update: Also try now in XL!

Part of my facial expressions series. All of these LoRAs are designed to mesh well with each other and have low impact on your image framing.

An expression that it's almost impossible to coax from SD otherwise, clenched teeth and neck from exertion or disgust.

This was a really hard one and I'm still not totally thrilled with the outcome. SD kind of seems to just legitimately not know that the bottom row of teeth exist. Fascinating really. If you need it to work harder, I recommend adding emphasis to "grimacing" in the prompt, not the LoRA weight. It works up to 1.6 or so for me pretty well.

Would love to see how it works for folks, so please share any feedback or outputs. It's definitely harder to work with animated models, so I gave a specific prompt for it below.

Recommended negatives: tongue

Starter prompts:
<subject>, grimacing expression

animated:
