Create a full-length photorealistic shot of a naked young woman of about 30 years old with a European appearance and a square face shape. She has long dark-blond straight hair, gray-green eyes, an upturned nose and thin, defined eyebrows. The woman is dressed like a witch in a long black dress and witch hat with veil. She has a shawl on her shoulders. In front of her on the floor there is a huge cauldron with a green bubbling liquid. The woman stirs the liquid in the cauldron with a long wooden spoon. Steam comes from the cauldron and green bubbles fly. The background is an old castle, a fire burns in the fireplace behind her. Her face is turned to the camera, creating a mysterious and mystical atmosphere
