Young Woman in Wooden Onsen Bath

A vertical 2:3 knee-up realistic portrait of a [woman in her 20s] relaxing in a shallow [wooden semi-open-air bath], positioned slightly to the right of center. She sits naturally with both hands resting on the smooth stone tub edge, her posture relaxed and graceful. Water reaches around her waist with delicate ripples spreading outwards. Subject and Expression: Bright ivory-beige skin with authentic texture, visible pores, subtle flush on the cheeks, and tiny water droplets. She looks toward the camera with a calm, gentle smile. Natural makeup with pale rose blush, soft pink-brown eye shadow, light brown eyebrows, sheer pink-beige lips, and delicate catchlights in clear eyes. Damp milk-tea ash brown medium-long hair with see-through bangs, styled neatly with loose strands framing her face. Clothing: [A modest ecru white spa towel wrap] secured securely and neatly across her chest, featuring natural cotton texture. Setting and Lighting: A serene Japanese-style semi-open-air bath framed by aged wooden pillars, bamboo screens, and soft green foliage in the background. Transparent hot bathwater with soft light reflections. Warm natural light falls softly from the upper left, highlighting her cheekbones and glistening water drops, with gentle ambient fill from the wooden walls. Camera and Style: 50mm lens equivalent, medium-close shot from a comfortable eye-level angle, shallow depth of field with creamy natural background blur, warm harmonious color palette of cedar wood, deep greenery, and teal water.
