Confident Asian Man in a Photorealistic Classroom

Photorealistic depiction of a confident Asian man in a classroom. He stands at the front by a dry-erase or smart board, addressing students with a calm, assured smile and direct gaze. He wears a tailored charcoal blazer over a crisp white shirt with no tie, dark trousers. Short black hair neatly styled, clean-shaven. The classroom is warmly lit with natural daylight from large windows; visible chalkboard or projector screen behind him; rows of desks and a few attentive students in the background. The shot has cinematic lighting, shallow depth of field focused on the man, detailed textures on fabric, skin, and hair, and realistic reflections on desk surfaces. The atmosphere conveys leadership and expertise.
