Art style: Cinematic Realistic.
Vertical 9:16 close-up cinematic portrait of Mr. Dalton, a 45-year-old tired chemistry teacher with thick round glasses and a rumpled white lab coat. His face shows visible irritation, eyebrows furrowed, thin lips pressed tightly.
He stands near a whiteboard covered in chemical formulas, fluorescent classroom lighting casting flat unflattering light on his face. Realistic skin texture, sweat sheen on forehead, cinematic dry-comedy tone, shallow depth of field, 4K. Крупный план

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Cinematic Realistic" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Cinematic Realistic". 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 "Cinematic Realistic" idiom, not in any other medium.
