Controlling the exact orientation of the hand is extremely difficult when recreating scenes of characters covering their mouths using standard image generation models.

Particularly when using existing tags like hand_over_own_mouth, there is a strong bias toward generating depictions where the back of the hand faces the mouth or the hand merely touches the face without firmly covering it.

This LoRA assists in generating scenes where the character firmly covers their mouth with their palm, ideal for expressing stifled voices or holding back nausea.
