Evil goat mask woman with black demon wings AI Image Prompt

Based on the original video, add a pair of huge, flapping black demon wings to the woman wearing an evil goat mask. The wings should have realistic leather texture, clear skeletal structure, and torn edges, spreading broadly from her back. Design a rhythmic and powerful flapping effect, showing a heavy and majestic visual impact. The wings must be precisely anchored to her torso and perfectly synchronized with her body's tilt or rotation, while casting natural shadows on her back and surroundings. Also add a creepy horror background music to the video to create an intense sense of oppression. During the addition of the above elements, the woman's original pose, goat mask, background environment, and camera movement trajectory must remain completely unchanged.
