Portrait, realistic, illustration, retro, warm

Create a realistic vertical lifestyle fashion portrait, featuring an East Asian adult woman aged 21 or older, standing inside a sunlit vintage commuter train or old-style bus, leaning beside a large open window. The framing runs from the upper part of her thighs to her head, positioned slightly to the right. Her torso faces the camera, her hips turn slightly toward the window, forming a natural S-curve. She leans lightly against the beige inner wall beneath the window, arms extended—one hand resting on the metal window sill on the left, the other on the window frame on the right. Her shoulders are relaxed, she looks directly at the camera with a warm, confident expression and a subtle, natural smile. She has long dark brown hair with soft layers and a slight side part. A strong wind blows in through the open window, dramatically blowing her hair toward the right side of the frame. In the sunlight, several strands glint as they flutter in the wind; fine hairs fall gently across her forehead, cheeks, and shoulders, and her long hair sways gently in the wind. Her makeup is refined and natural: fair, translucent skin, soft peach blush, well-defined brows, light brown eyeliner, long curled lashes, subtle contouring, and soft rose-pink lip gloss. She wears a light ivory cropped top made of thin, semi-sheer fabric, dotted with tiny peach or coral polka dots. The top has short puff sleeves with soft elastic cuffs, a deep V-neck wrap design, shirred seams, and a front tie that reveals just the right amount of skin at the waist. Paired with fitted deep indigo denim shorts with a high-waisted design, rolled cuffs, gold contrast stitching, belt loops, metal buttons, front pockets, and small embroidered details near the pockets. The jeans should show realistic fading, stitching, texture, and slight wrinkles around the hips. The scene should simulate the interior of an old train car or vintage public transport, such as beige metal wall panels, exposed screws and seams, a large rectangular sliding window with brushed aluminum trim, and a dark navy blue vinyl bench visible in the lower right corner. Through the open window, a sunny suburban street can be seen: light-colored buildings, lush greenery, roadside scenery, and muted-toned vehicles, all rendered with shallow depth of field and slight directional motion blur, suggesting the vehicle is moving. Strong natural light comes in from the upper left and behind the subject. A soft rim light forms around her hair and shoulders, with bright highlights on her cheekbones, arms, waist, shirt, and jeans, filled by soft light reflected from the light-colored inner wall. Subtle shadows under her chin, around her waist, and in the clothing folds are preserved to enhance depth. The overall atmosphere should be fresh, cool, and full of summer, natural yet slightly nostalgic, like a refined travel photo taken during a daytime journey. Camera and composition: vertical 2:3, eye level or slightly low angle, about 50mm lens, shallow depth of field, subject in sharp focus, background softly blurred, subtle sense of motion in the hair and background, realistic perspective, balanced composition, the large window forming a bright rectangular frame around her. Maintain natural human anatomy, realistic hands and fingers, accurate fabric texture, delicate skin texture, and use warm ivory, sunlit beige, deep indigo, soft green, and pale peach for cinematic color grading. Style: realistic travel photography, adult model, cool train window portrait, bright natural sunlight, windblown hair, white front-tie cropped top, dark denim shorts, vintage subway interior, natural summer atmosphere, realistic skin and fabric texture, high detail, clean composition, no text, no watermark, no logo, no other people, no distorted anatomy, no duplicated limbs, no artificial plastic skin, not cartoon or illustration style, no harsh flash, no excessive blur, no explicit nudity.
