Wanted to see how well it would work considering the somewhat lacking dataset. Can be attached to body, honestly it's harder to get her to be floating disembodied sometimes. inpainting will be your friend with this LoRA if you wish to have it as accurate as possible ("featherduster" is a somewhat broken prompt unless you wish to spend a fair amount of time)
Trigger: Dusa, gorgon
No body: Disembodied head, neckless
Body: body (Lamia body might work)
helpful: bandage, medallion, snakehair, blush, floating
