Use the input image as the exact first frame. Preserve the original image exactly. Maintain identical framing, composition, perspective, camera angle, focal length, lighting balance, background, facial proportions, skin texture, hand anatomy, finger placement, ring position, gemstone proportions, gemstone cut, prong geometry, band thickness and every jewelry detail. The camera remains completely locked. No zoom. No dolly. No pan. No tilt. No orbit. No handheld movement. The hand is completely rigid. The fingers are completely rigid. Every finger remains locked in its exact original position. Finger joints are locked. No finger flexing. No finger extension. No finger sliding. No finger rubbing. No finger pressure change. No finger repositioning. Maintain identical fingertip contact points throughout the entire shot. The hand behaves as a rigid object. The ring behaves as a rigid object. The jewelry never moves. The ring never rotates. The gemstone never rotates. The gemstone never changes shape. The prongs never deform. The band thickness never changes. The only body movements are: A very slow, smooth head tilt approximately 2 degrees to the left while maintaining the same posture. One slow natural blink during the middle of the shot. A barely perceptible soft smile that develops naturally after the blink. The smile is extremely subtle, with only a slight upward movement of the mouth corners. No teeth visible. No exaggerated facial expression. The eyes remain locked directly into the camera with a clear, sharp, confident gaze throughout the entire shot. Lighting animation: The studio lighting remains fixed, but a narrow soft specular light sweep slowly moves across the diamond from the upper-left facet toward the lower-right facet during the final third of the shot. The sparkle is created only by the moving light. The gemstone, ring and hand remain perfectly static. Create multiple crisp white specular highlights and realistic internal reflections inside the diamond. The gold band receives subtle moving reflections while remaining completely motionless. Everything else remains perfectly frozen. No facial morphing. No AI hallucinations. No object replacement. No object deformation. No additional gestures. Ultra-realistic luxury jewelry commercial. Premium beauty campaign. Stable anatomy. Stable jewelry. Physically accurate diamond reflections.
