Demonic nun in shadowy robes

A tattoo design of a sinister, demonic nun who exudes menace and mystery. Her face is deformed and skeletal, with empty eye sockets that glow with a soft, sinister light from beneath the tattered veil of her nun's habit. The nun's hands are distorted, resembling claws, and are clasped in mocking prayer. Her emaciated body is wrapped in flowing, shadowy robes that blur into ethereal, ghostly ribbons. The background of the design is filled with swirling smoke and subtle, sinister symbols that enhance the atmosphere of darkness and mystery. The design features richly detailed decay, dynamic shading, and a dark atmosphere, done in black and gray.
