Prompt

Create a smooth looping cinematic animation from this still illustration. Keep the character's appearance, face, proportions, outfit, colors, lighting and composition exactly the same. Animate only subtle idle movements. The ocean background gently ripples with realistic shimmering water reflections and soft caustic light. The character breathes naturally with a very subtle rise and fall of the shoulders and upper torso. Her long side braid slowly sways underwater with gentle floating motion, while the loose front curls softly move. The necklace chain swings delicately with physics, and her hand lightly adjusts and holds the pendant as if protecting it, with minimal elegant finger movement. Small sparkling highlights travel across the pearls, shell top and gemstone. Add tiny floating light particles in the water. Maintain a dreamy underwater atmosphere, soft bloom, high detail, anime illustration quality, no camera movement, no scene changes, no facial distortion, no body distortion, seamless 5-second loop at 24 fps.
