Wisdom in Warmth: A Teacher's Portrait

Create a portrait of a male Asian teacher in a warmly lit classroom setting. His face is expressive, showcasing a gentle smile that radiates warmth and approachability, with deep-set brown eyes reflecting wisdom and patience. He has short, neatly styled black hair with subtle gray strands, hinting at experience. The lighting is soft and diffused, casting a golden hue that enhances his skin tone and creates a serene atmosphere. He is wearing a smart-casual outfit: a light blue button-up shirt with the sleeves rolled up and a dark blazer. The background features a chalkboard filled with colorful educational diagrams, and a few bookshelves lined with books. The composition is framed in a medium shot, focusing on his upper body, with a shallow depth of field to softly blur the background. Render in a realistic style, reminiscent of contemporary portrait photography, with attention to detail in texture and light.
