Vertical 9:16, a candid real-life photo taken with an iPhone 1x main camera during a journey. A friend who just woke up in the upper bunk across from her leans out from the edge of the bed and takes a photo looking down. The camera is positioned diagonally above her, high-angle shot; the top right corner of the frame includes a section of the upper bunk's aluminum guardrail and a corner of a white quilt, with the foreground completely blurred.

Character: She is a Shenhe coser from Genshin Impact, an East Asian female in her early twenties, clearly an adult. Her aloof facial features are softened by her just-woken-up state, possessing the beauty of a professional photo model. A small face, a delicate bridge of the nose, and a sharp, clean chin; almost no makeup, only the sheen of some lip balm and very faint eyebrows; realistic skin texture, with tiny pores on the bridge of the nose and cheeks, eyelids slightly puffy from sleep, and a shallow pillow mark pressed into one cheek.

Identifying Features: Long silvery-white hair reaching the waist, with a few strands sticking up at the crown from sleep; ice-blue pupils; a thin red cord braided into her hair, with the other end loosely wrapped around her wrist.

Body: Tall and slender, full chest, thin waist, with long and well-proportioned lines from the thighs to the knees.

Outfit: An oatmeal-white oversized chunky cable-knit sweater worn as a sweater dress, the hem just covering the upper thighs; the neckline is too large, sliding down on one side to reveal the collarbone and one shoulder. On her legs are black over-the-knee thick cotton socks, with the sock tops creating a very shallow indent in the soft flesh of the thighs. No shoes.

Legs: The legs are the highlight. She has one leg tucked in and the other leg stretched out along the edge of the bunk; a section of fair thigh is exposed between the top of the over-the-knee socks and the sweater hem, with the snowy light casting a cold white highlight along the straightened calf.

Action: She is sitting in the lower bunk by the window, back against the partition, holding a thermos with both hands on her knees, turning her face to look at the snowy plains outside the window, her expression quiet, as if dazed.

Lighting: Early morning, outside the window is a snow-covered plain, just after dawn, the snow reflecting cold white skylight into the carriage, illuminating her face, collarbone, and legs from the side, making the edges of her silver hair almost transparent; only a small warm yellow reading light is on above the bunk in the carriage, leaving a touch of warm color on the top of her head and the shoulder of her sweater. Cold and warm light meet on her body, with the shadow side leaning towards bluish-gray.

Environment: An old-fashioned green train soft-sleeper compartment, dark green faux-leather bunks, white sheets, quilts folded into "tofu blocks"; on the small table by the window sits a bag of opened oranges, half a peeled orange, and a folded train ticket. On the snowy plain outside, there is a row of distant utility poles and a lonely tree, rushing past.

Texture: Real mobile phone photo, overall cold blue-gray tone, with a small warm orange patch from the reading light; focus on her side profile; the carriage shakes slightly, causing a bit of motion blur in the utility poles outside, with slight mobile phone noise at the edges of the frame.
