Un peintre de la Renaissance travaille sur la Joconde dans son atelier

A highly detailed photorealistic historical scene inside a rustic Renaissance artist's studio with rough stone walls, wooden ceiling beams, and soft natural light coming through a leaded glass window. An elderly male painter with long gray hair and a full gray beard, seen from behind, wearing a long brown velvet Renaissance robe with a leather belt, is standing at a wooden easel and carefully painting with a fine brush. On the easel is the famous Mona Lisa painting in progress, showing the iconic portrait of a woman with a subtle smile against a misty landscape background. To the right of the easel sits the real life model, a beautiful young woman with dark hair pulled back, wearing a period-accurate olive-green Renaissance dress with brown sleeves and white lace collar, smiling gently at the viewer while posing on a simple wooden stool. An oil lamp glows warmly on a small wooden table beside her. In the foreground, an open wooden paint box filled with brushes, pigments, and tools rests on a stool. Atmospheric, warm cinematic lighting, rich textures, highly detailed, masterpiece, 8k, photorealistic.
