Stylish White Man in a 3D Classroom Scene

A stylish White man in his early 30s stands beside a desk in a modern classroom. A high-quality 3D render with photorealistic textures, realistic skin shading and fabric detail. He has short brown hair with light stubble, wearing a tailored charcoal blazer over a crisp white shirt with the top button open, and dark slim-fit chinos with brown leather loafers. The classroom features a glass whiteboard, laptops on polished desks, and soft natural light from large windows. Subtle reflections on surfaces, cinematic lighting, shallow depth of field with a gentle bokeh, cool neutral blues and grays to emphasize a contemporary academic setting.
