Wisdom in Warmth: A Teacher's Portrait - Flux.1 schnell

Create a portrait of a South Asian male teacher, aged around 40, with warm brown skin and expressive dark brown eyes that convey wisdom and kindness. His hair is short and slightly tousled, with flecks of gray. He wears a smart, casual button-up shirt in soft blue, and a light cardigan. The setting is a cozy classroom filled with books, with soft, natural light streaming in from a nearby window, casting gentle shadows that enhance the warmth of the scene. His expression is one of encouragement, with a slight smile that invites engagement. The composition should focus on his upper body, with a shallow depth of field to blur the background slightly, emphasizing his figure. Render in a realistic style, akin to contemporary portrait photography, using a 50mm lens to capture fine details and textures, ensuring the mood is both inviting and inspiring.
