A digital illustration of a teenage boy sitting happily at his desk in a bright and lively classroom, wearing his iconic blue jacket over a beige shirt and beige pants. He has a relaxed smile as he listens attentively to the front of the room. Around him, many classmates--boys and girls--are sitting at their desks, dressed in a variety of colorful casual clothing, creating a vibrant and diverse atmosphere. The classroom is modern and filled with soft morning light coming through large windows, with educational posters, a whiteboard, and rows of organized desks. The illustration is vivid, clean, and highly detailed, with warm lighting, dynamic composition, and consistent character design and style. --cref <https://s.mj.run/camwF07Bd04> --ar 16:9
