Create a 9:16 35mm film-style editorial portrait of a clearly adult woman in a warm vintage Japanese onsen ryokan. Use soft wooden lantern light mixed with gentle natural window light, subtle film grain, warm color shift, and an intimate but tasteful medium shot. The subject has refined East Asian features, porcelain skin with natural texture and micro pores, soft natural makeup, rosy cheeks, natural pink lips, and long dark-brown hair tied in a loose low bun with a few relaxed strands around the face and neck. She wears a loose white yukata tied at the waist, softly draped at one shoulder while keeping the composition tasteful and non-explicit. She sits barefoot on the edge of a traditional wooden engawa veranda, body turned slightly toward the camera, one leg bent on the wooden floor and the other relaxed, one hand lightly holding the yukata collar and the other supporting her on the floor. In the background, show warm wooden interiors, paper sliding doors, and a distant steaming hot spring in soft focus. Use gentle rim lighting to highlight skin texture, hair strands, and realistic yukata fabric wrinkles. Keep the mood serene, cinematic, elegant, and inviting without nudity, explicit sexual framing, transparent clothing, fetish emphasis, voyeuristic angle, underage appearance, plastic skin, over-sharpening, airbrushing, watermark, or text. Output aspect ratio: 9:16.
