Gaunt humanoid with hollow empty eyes and no mouth, inspired in Sandman from Sleepy Hollow TV Series.
It's a freshly baked LoRA. I will be updating the best generation prompts and resources, sorry for the inconvenience.
You can try this for now:
... white bald gaunt humanoid with pale skin, empty hollow eyes and no mouth ...
It's hard to get mouthless generations, try strength: 1,1 for now.
Be careful with Detail LoRAs as they could try to add mouth and eyes...
