Use the uploaded image as the exact visual reference. Preserve the original female subject, facial identity, hairstyle, outfit, accessories, body proportions, lighting, background, camera angle, framing, composition, and color tone exactly as they appear in the source image. Do not add, remove, replace, redesign, or restyle anything. Do not change the background, environment, clothing, props, lighting, or camera setup. Only animate the subject's facial expression, head movement, shoulders, subtle upper-body posture, hair movement, and natural clothing motion. Animate the woman with the same "radiant grin" motion from the reference video. The subject stays in the same position throughout the video. She does not walk, turn around, raise her hands, dance, or change location in the frame. The camera remains close, front-facing, and focused on her face and upper body. The motion begins with the woman facing the camera with a soft, calm, slightly playful expression. Her lips are gently closed or only slightly smiling. Her eyes look directly into the camera with relaxed confidence. Then her expression slowly brightens. Her cheeks lift, her eyes become warmer and slightly squint with happiness, and her smile gradually opens into a big radiant grin. The smile should feel natural, charming, and genuine, like a beauty portrait coming to life. As the smile grows, her head makes a subtle tilt to one side, then gently shifts back with a tiny natural sway. Her chin lowers slightly for a cute, intimate feeling, while her shoulders softly relax and move with the expression. The movement is small and delicate, not exaggerated. Her upper body may lean forward very slightly toward the camera, creating a warmer and more engaging portrait moment. The motion should feel like a spontaneous happy reaction, not a posed commercial smile. Hair moves only subtly from the small head tilt and shoulder motion, softly shifting around the face and shoulders. Clothing reacts minimally and realistically to the upper-body movement. The final pose holds the bright smile for a moment, with direct eye contact, lifted cheeks, relaxed shoulders, and a warm, glowing, confident expression. Camera behavior: keep the original camera angle and framing unchanged. No zoom, no cuts, no camera rotation, no background movement, and no new visual effects. The only animation should be the woman's facial expression changing into a radiant grin, plus subtle head tilt, shoulder movement, upper-body micro-sway, hair motion, and natural clothing motion. Motion sequence: 1. Front-facing close portrait pose. 2. Soft calm eye contact with a slight smile. 3. Smile gradually grows wider. 4. Cheeks lift and eyes brighten. 5. Subtle head tilt and tiny shoulder movement. 6. Slight natural forward lean. 7. Hold a big radiant grin while looking into the camera. The final video should look like the original still image naturally comes to life with a warm, glowing smile, while every non-motion visual element remains completely unchanged.
