Boudoir portrait of Yuna, a fictional twenty-seven-year-old woman with black hair in a sleek low bun, wearing a jade-green satin corset with ivory lace and an open white robe, standing beside the spring basin in soft morning light. The setting is a spring-house studio where a plain stone spring basin of clear water sits beside the posing bench. Every prop is plain, smooth and completely unmarked: no text, no letters, no numbers, no symbols, no logos, no charts, no markings or graduations anywhere in the image. Warm cinematic light, photorealistic, full-length composition, an elegant mature woman.
