Art style: stikman.
An elderly gentleman in his 70s with a gentle, professorial air and thinning gray hair. He is wearing a cozy, navy blue wool V-neck sweater over a light blue collared shirt. He is seated in an expansive, high-ceilinged private library filled with floor-to-ceiling wooden bookshelves packed with antique books. The room is bathed in the warm, golden light of a late afternoon sun streaming through large windows, highlighting his calm and thoughtful expression. He has a peaceful, meditative energy, with his hands resting comfortably on the arms of a leather chair, surrounded by the quiet atmosphere of a lifetime of study.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "stikman" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "stikman". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "stikman" idiom, not in any other medium.
