現有光線

Use Available Light: use only the existing sky daylight, sun outside frame and natural courtyard reflections, with no additional photographic light. Change the daylight condition to a clearly directional afternoon sun entering from upper camera-left, producing a consistent single cast shadow toward lower camera-right, plus cooler natural sky fill in shadows. Keep the existing lantern off. Preserve every original cloud position and contour, recoloring only illumination, and preserve all original subject placement and geometry.
