[
  Subject and State
] A hyper-realistic mobile phone snapshot,
presenting a quiet,
tired,
and natural moment during a journey. In the right foreground of the frame,
an adult East Asian woman is asleep in a blue aisle seat of a Chinese high-speed rail second-class carriage. She has a black bob haircut,
her head is slightly tilted toward her right shoulder,
her eyes are closed,
and her expression is calm and natural,
without any sense of deliberate performance. She is wearing a light blue-gray off-the-shoulder knitted top and an off-white short skirt. Her arms are naturally crossed in front of her,
and her legs are naturally together and slightly slanted. Her overall posture is relaxed,
as if she has inadvertently fallen asleep due to exhaustion during the train journey. The character's state should be real and restrained, with skin retaining natural texture and real quality, without excessive beautification or skin smoothing, presenting the sense of life of an ordinary mobile phone snapshot. [Second Character and Background Characters] In the middle ground on the left side of the frame, another adult East Asian woman in a window seat is also in a state of sleep. She has long black hair, her head is tilted against the window, her eyes are closed, and she is wearing a white shirt and a dark gray short skirt, sitting quietly in a blue window seat. A black bag is placed beside her as an everyday travel item to enhance realism. An empty seat is kept between the two people, allowing the blue seats to form a clear depth-of-field relationship. A few ordinary passengers are scattered in the back row of the carriage, some partially blocked by seats, existing only as background elements, not overshadowing the main visual center. [Appearance and Outfit] The foreground subject is an adult East Asian woman with an ordinary and real temperament, with a natural appearance, without exaggerated influencer-style modification. Her cold brown bob hairstyle has a slightly natural fluffy feel of daily life. The outfit is simple and daily, a light blue-gray off-the-shoulder knitted top paired with an off-white short skirt, the overall atmosphere is a relaxed, daily, and real travel outfit. The woman in the left middle ground has long black hair, wearing a white shirt and a dark gray short skirt, also maintaining the natural image of an ordinary passenger, without deliberate sexualized presentation. Both characters should reflect the state of tired rest of real East Asian women during a journey, rather than a sense of a posing model. [Environment] The scene is set inside a Chinese high-speed rail second-class carriage. The interior features typical blue fabric seats, each equipped with a white headrest cloth, and real and reasonable seat number text is visible on the wall above. The overall space should be clean, bright, and tidy, with the structure and atmosphere of a real high-speed rail carriage. A blurred platform and urban tracks are visible outside the window as external hints of the high-speed train environment, but they should not be too clear or eye-catching. The entire environment should convey the sense of order and life of a real public transportation space, and no wrong carriage structures or chaotic backgrounds should appear. [Composition Requirements] Adopt a vertical composition, 3:4 ratio, the overall look is like a mobile phone lifestyle photo captured unintentionally during a journey. The sleeping woman in the right foreground is the main visual focus, and the sleeping woman by the window in the left middle ground forms a resonance. The empty seat in the middle and the rows of blue seats together constitute a clear spatial depth, allowing the internal structure of the high-speed rail carriage to unfold naturally. The texture of the blue seats, white headrest cloths, windows, seat numbers, characters' sleeping postures,
and scattered passengers in the back row should be naturally presented in the frame. The composition can have a slight sense of snapshot and slight imperfection,
without being too neat,
to strengthen the documentary atmosphere of "unintentionally captured during a real journey." The visual focus is suggested to fall in order: the sleeping woman in the right foreground -> the sleeping woman by the window in the left middle ground -> the depth formed by the blue seats and empty seats -> the white headrest cloths and seat numbers -> the blurry window exterior and back row passengers. [
  Camera/Technical Parameters
] The overall look should present a hyper-realistic mobile phone photography quality,
as if naturally taken with an ordinary mobile phone,
rather than a professional studio shoot. Use a slight wide-angle perspective to retain the sense of carriage space and the longitudinal extension of the seats. The optical performance should be close to daily mobile phone imaging: the subject is clear,
the background and the window exterior can have a slight natural blur,
with a bit of slight noise and the sense of daily image compression. The frame retains real skin details,
clothing folds,
seat fabric texture,
headrest cloth texture,
and carriage structure details,
avoiding over-sharpening,
over-smoothing,
or a fake high-definition feel. [
  Atmosphere/Light
] Adopt real natural indoor light,
mainly the ambient light inside the high-speed rail carriage,
without using cinematic lighting or studio-style light effects. The overall light should be naturally soft,
bright,
and restrained,
like the real light sense formed by the outside of the window and the carriage lighting when the train is moving or stopped during the day. The area outside the window can be slightly brighter but not overexposed; the characters' faces and clothing should be naturally lit, retaining a quiet, tired, and life-like atmosphere. The overall color tone should be realistically neutral, without strong filter processing, to strengthen the "unintentional snapshot during a quiet journey" temperament. [Style] The overall style is realistic documentary photography, mobile phone snapshot, and lifestyle snapshot style. Emphasize the sense of real moments in public transportation scenes, rather than fashion photography, posed blockbusters, or movie stills. The image should have a clear realistic photography tendency, retaining the simplicity, restraint, and daily sense of ordinary mobile phone photos, avoiding a heavy sense of AI generation. The final effect should make people feel that this is a lifestyle photo accidentally taken during a real high-speed rail journey. [Detail Emphasis] Focus on the following details: The real spatial sense and structure of a Chinese high-speed rail second-class carriage; The material details of blue fabric seats and white headrest cloths; Reasonable and real seat number text on the wall overhead; Blurred platform and urban tracks outside the train window; The tired sleeping posture of the woman in the right foreground with her head slightly tilted, eyes closed, arms naturally crossed, and legs naturally together and slanted; The posture of the woman in the left middle ground sleeping by the window and the black bag beside her; The presence of passengers in the back row as background elements should be low, used only to enhance the real atmosphere of the carriage; The overall performance should be a quiet, tired, restrained, and natural state of life during a journey; The photo must look like a real capture, not a deliberately designed, over-modified, or image with obvious AI traces. [Avoid] Low quality, poor clarity, blurry face, deformed face, deformed hands, deformed legs, extra fingers, missing fingers, hand errors, body proportion errors, facial distortion, eyes open, fake skin, plastic texture, over-smoothing, over-beautification, influencer photo sense, deliberate posing sense, studio sense, movie lighting, strong filters, over-sharpening, over-saturation, sexualization, nudity, minors, school uniforms, suggestive poses, provocative expressions, exaggerated body figures, low-cut emphasis, anime style, illustration style, CG feel, 3D rendering, oil painting style, garbled text, wrong seat numbers, wrong carriage structure, duplicate characters, multiple heads, multiple legs, multiple hands, chaotic background.
