Skull Bird(骸骨鳥) from [Sogna] Viper RSR character lora.

When it comes to the skull mask, it seems you either have to specify "red eyes," for the skull to have the correct eyes, or put "eyes," in the negative prompt and not use an eye ADetailer model.

Trigger words:

(ViperRSRSkullBird:1.2), harpy, monster girl, breasts, nipples, female pubic hair, large breasts, winged arms, black feathers, navel, nude, skull mask, purple lipstick,

Some of these tags might be superfluous, but I haven't figured out which.

Head tends to be a bit on the long/tall side.
