20-year-old young adult East Asian woman sitting in the passenger seat of a car

9:16 vertical, hyper-realistic mobile phone selfie photo, real iPhone 17 Pro front camera casual selfie effect, a friend temporarily raising the phone to capture during a trip, no composition, no posing, no portrait shoot feel, like the most ordinary everyday photo in a phone album. \n \n A 20-year-old young adult East Asian woman sitting in the passenger seat of a car, red leather seat background, long straight black hair with airy bangs, fair skin, natural light makeup, relaxed slight smile looking at the camera. \n \n Wearing blue denim overalls, natural deep V neckline, right hand lightly pinching a cute sperm whale-shaped gold pendant necklace on her chest, left hand holding the phone for a selfie. She has a full, natural, well-proportioned mature figure, approximately F-cup visual effect, breasts naturally sagging under gravity, slim waist and full hips, overall proportions realistic. \n \n Arm fully extended for the selfie, lens very close to the face, forming a realistic mobile phone selfie perspective, the image is slightly tilted, the person is not centered in the frame, the top of her head is slightly cropped, one arm occupies a prominent foreground. \n \n The car is traveling at high speed, outside the window trees, guardrails, roads, and vehicles all form natural horizontal motion blur, only the person's face remains clear, hair strands flutter slightly, sunlight shines into the car from the side window, natural light and shadow, no fill light. \n \n Retain real pores, tiny imperfections, slight exposure fluctuations, slight hand shake, slight focus error, a small amount of HDR computational photography traces, overall like a casual selfie taken by a friend during a trip, not AI-generated.
