Wisdom in a Warm Smile

Create a portrait of a male African teacher, exuding warmth and wisdom. His facial features include deep-set, expressive brown eyes, a broad nose, and a warm smile that reflects kindness and approachability. He has short, neatly styled hair and a well-groomed beard. The lighting is soft and natural, casting gentle highlights on his face, suggesting a sunlit classroom. The composition centers him against a backdrop of chalkboards filled with colorful diagrams and books, symbolizing knowledge. His attire is smart-casual, featuring a light blue shirt and a patterned tie, hinting at his professional dedication. The mood is inspiring and uplifting, reminiscent of the realism of 19th-century portraiture. Use a 50mm lens for a shallow depth of field, focusing on his face while softly blurring the background, enhancing the intimate connection with the viewer. Render in high resolution with vibrant colors to capture the essence of his character.
