A Classroom in Shared Rhythm

Animate this image into a smooth, realistic 3D cartoon educational video. The female teacher stands in front of the classroom and explains the lesson with natural hand gestures, pointing to the board while teaching. The students sit at their desks, look attentively at the teacher and the board, nod gently, and write notes in their notebooks. One student raises a hand to ask a question, and the teacher responds with a warm smile. Add natural blinking, subtle head movements, and gentle body movements. Use a slow, smooth camera movement to show the teacher and students. Keep the same characters, faces, clothes, classroom layout, desks, and lighting as the original image. Maintain a cheerful, welcoming tuition-class atmosphere. High-quality 3D cartoon animation, smooth motion, consistent characters, horizontal 16:9 composition. No sudden movements, no scene changes, no extra people, no distorted hands, no changing faces, no flickering, and no additional text. No dialogue or background music.
