Prompt
A teacher walks slowly towards the camera with natural and realistic motion. Their steps are steady and deliberate, with slight arm movement matching the walking rhythm. As they get closer, their facial expression transitions smoothly into a warm, genuine smile. After a brief pause, the teacher leans slightly forward towards the camera in a friendly, engaging manner, creating a sense of closeness and connection. The upper body subtly shifts forward during the lean, with slight head tilt and natural eye focus towards the lens.
