Realistic Social Media Style Portrait

Vertical mobile photography, real-life snapshot style. A young gender_and_ethnicity sitting by the window in a quiet and cozy setting, sitting naturally to the side and leaning forward slightly, elbows resting on the edge of the table, facing the camera with a natural, happy and slightly shy smile, eyes bright and spirited, like a spontaneous moment captured when a friend suddenly asked her to look at the camera. She has naturally falling long straight black hair, middle-parted, slightly fluffy with a few stray hairs, wearing a clothing, the clothing is soft and fitted but not overly emphasizing the figure. The left hand holds a paper bowl of light green ice cream or dessert, and the right hand holds a small spoon, the action naturally stopping at the moment of being ready to take the next bite. Sitting on a light yellow fabric sofa, the background is wooden window frames and translucent glass with vertical ridges, with soft green plants vaguely visible outside the window. The left side is a creamy white wall, the tabletop is a dark old wooden table, and a few small doll ornaments are placed in the corner. The indoor environment is quiet, clean, and full of life, not a luxurious restaurant feel. Natural window light enters from the upper right behind the subject, the face exposure is bright and soft, the skin tone is naturally warm, retaining real skin texture, slight pores, small imperfections and natural luster, no skin smoothing, no plastic skin. Black hair retains clear layered strands, with slight backlighting at the edges of the face. Shot using a standard mobile phone rear camera, about 26mm wide-angle perspective, medium-close-up composition, the lens slightly higher than the subject's eye level, slight high-angle shot, the subject's face located in the upper-middle area of the frame. The composition is slightly casual, arms and skirt naturally enter the frame, with slight mobile wide-angle perspective, but no obvious distortion of the face. The overall look presents a real social media life photo, a friend's snapshot, a natural atmosphere without professional lighting. Slight warm tones, low contrast, soft highlights, subtle mobile noise reduction marks, partial slight overexposure, clear image but not over-sharpened, no cinematic feel, no studio feel, no influencer-style over-editing, authentic and natural, highly realistic.
