Портрет в стиле 15-го века

Restyle this portrait as an oil painting from the 15th-century Northern Renaissance. The man is depicted as a learned scholar in his study, looking thoughtfully at a world map. CRITICAL FOR FACE AND HAIR: Transfer face exactly 1:1 from the uploaded photo. Preserve identical facial features (eyes, nose, lips, jawline, eyebrows), skin tone, and the EXACT same hair — same color, same length, same texture, same hairstyle as in the reference. Do not change hair color under any lighting condition. Maintain identical body proportions and build. Wardrobe: A heavy olive-green wool doublet with fur lining, a pristine white linen collar, and a dark cap. Setting: A dark wooden desk with a quill, an hourglass, and a leaded glass window showing a medieval city view. Lighting: Side-lit Rembrandt lighting from the window, deep shadows, fine oil impasto texture, craquelure effect. Authentic Renaissance aesthetic, pensive and regal mood. Shot like a gallery masterpiece, 8k, sharp focus on eyes. NEGATIVE: no face distortion, no hair color change, no extra fingers, no plastic skin, no blur, no oversaturation, no franchise references, no brand logos, no nudity, fully clothed. Full body visible, centered composition, nothing cropped at edges.
