Anime Girl Sprite Sheet Animation

Create a 24-frame sprite sheet arranged in a 6x4 grid on a solid black background. The subject is an anime-style girl with short silver-white hair, wearing a light blue and white outfit with floral accents. She has a cute expression with closed eyes (happy squint) and hands cupping her cheeks. Generate 24 distinct frames showing subtle variations of this pose to create a smooth animation loop when played at 8 FPS. Ensure the character's position remains consistent within each cell for easy slicing.
