Anime Man with Glasses

Modern anime key visual, clean thin line art, flat cel shading, vivid colour, dramatic lighting. A head-and-shoulders portrait of a man in his thirties with dark hair, round glasses and a warm smile, knitted sweater, autumn background. Any person shown is an adult in their late twenties or older, drawn with adult proportions, realistic eye size and a mature face; an original character. No text, no letters, no logos, no watermark.

Prompt tip: Name the light source — rim light, sunset, neon — and the key visual look follows.
