Ultra-photorealistic casual smartphone selfie of a young East Asian woman seated near a sunlit window inside a quiet room. Preserve a strong resemblance to the facial reference, including a softly contoured oval face, gentle jawline, naturally proportioned nose, realistic lip shape, balanced eye placement, subtle facial asymmetry, and true-to-life skin tone. Facial features should appear authentic and unretouched, with visible pores, fine skin texture, and natural imperfections. Avoid beautification filters, cosmetic enhancement, or stylized rendering. The subject is captured from a close, arm's-length perspective in a relaxed three-quarter profile, turning slightly toward the window while gazing outside. Her expression is thoughtful and understated, with calm eyes, relaxed facial muscles, and a naturally resting mouth. The overall mood feels spontaneous and unposed rather than editorial or glamorous. Her hair is long, dark brown-black, and naturally voluminous with soft texture and slight disarray. Individual strands and subtle flyaways are visible where the sunlight catches them, creating realistic backlit detail. She wears large circular black eyeglasses with glossy acetate frames that reflect the ambient daylight in a believable manner. Clothing consists of a simple fitted heather-gray cotton tee with realistic fabric texture, natural creasing, slight stretching, and accurate draping around the shoulders and upper body. The wardrobe should feel everyday and understated. Natural sunlight streams through the window from one side, creating convincing directional illumination and strong yet realistic contrast. Window-frame shadows fall across portions of the face and body, producing authentic bands of light and shade. Bright areas should retain realistic highlight behavior, subtle skin sheen, and natural color variation without HDR effects or artificial glow. The setting is minimal and believable: a light neutral wall, a clean vertical window frame, and no decorative distractions. The environment should support a quiet, intimate indoor atmosphere. Camera characteristics: realistic smartphone front-camera capture, vertical aspect ratio, slightly low selfie angle, arm partially visible in the foreground, mild wide-angle perspective distortion, realistic computational photography processing, gentle depth separation, authentic exposure behavior, subtle digital noise, slight lens softness, and natural contrast response. Composition: tight upper-body framing, subject positioned slightly off-center, window visible along the edge of the frame, candid snapshot aesthetic, imperfect framing consistent with a genuine handheld selfie. Priority: maximum realism, accurate anatomy, true skin detail, natural lighting physics, believable optical imperfections, authentic smartphone image quality, documentary-style appearance, no CGI look, no cinematic grading, no excessive sharpening, no influencer-style retouching, no anime or illustration characteristics.
