Léonard peignant la Joconde dans son atelier

A cinematic Renaissance art studio interior lit by soft warm window light, showing [an elderly Leonardo da Vinci-like painter] in left profile, seated at an easel and painting [the Mona Lisa] from a live model. The painter has long gray hair, a full gray beard, wearing [a dark period cap and heavy dark robe]. In the center foreground, a canvas on a wooden easel displays the work in progress, while on the right [a live female sitter poses in the iconic posture with folded hands, wearing a dark Renaissance dress and veil drapery]. The setting features aged plaster walls, a leaded-glass window on the left, a background wooden table with brushes and studies, and two portrait sketches pinned behind the model. In the lower right foreground, a painter's worktable holds a palette with dabs of paint, brushes in a cup, and shallow bowls. Medium-wide shot, slightly over-the-shoulder perspective from behind the painter, dramatic chiaroscuro with rich brown and amber tones, realistic historical atmosphere, soft focus falloff, no modern elements.
