Seated portrait — relaxed and natural

Generate a realistic candid lifestyle photograph of an adult woman with long, dark, naturally wavy hair falling over her shoulders, expressive dark brown eyes, soft natural makeup, and a genuine relaxed smile. She is wearing a simple fitted black dress with thin shoulder straps and minimal gold jewelry. She sits comfortably on a cream-colored upholstered sofa in a refined hotel lounge. Her body is turned slightly toward the camera, one arm resting on the sofa and the other gently brushing a strand of hair away from her face. Her expression feels spontaneous and unposed. Use a warm neutral interior palette with beige walls, natural stone surfaces, dark wood accents, and soft ambient lighting. Include realistic fabric creases, subtle skin imperfections, natural hair volume, and believable contact shadows where her body meets the sofa.
