Create an authentic 3:4 vertical smartphone photograph taken at an outdoor urban café. A young adult woman, approximately 20 to 26 years old, is sitting diagonally and deeply in a dark brown wooden folding chair. Her hips rest toward the rear of the seat, her back is lightly supported by the chair, and both knees are bent and drawn up onto the seat. One knee sits closer to the camera, producing a believable near-far perspective. She raises both arms above her head, bends her wrists softly and loosely brings her fingers together into an incomplete, slightly asymmetrical heart. The gesture should feel spontaneous and imperfect, as though she improvised it while talking rather than carefully posing. She has a chin-length warm chestnut-brown bob with airy straight bangs, lightly flipped-out ends and a few loose strands beside her ears. Direct sunlight falls across the crown, turning selected strands honey-gold and copper. The hair feels fine, soft, naturally voluminous and slightly disordered rather than salon-perfect. She looks directly upward toward the camera with bright eyes, subtle catchlights and gently raised outer corners. Her lips remain softly closed, with only a restrained upward curve, suggesting she might laugh in the next second. Preserve her authentic facial proportions and avoid turning her into a generic influencer face. Use lightweight everyday makeup inspired by contemporary Korean and Japanese beauty-editorial styling: natural straight brows, fine soft-brown eyeliner, subtly defined lashes and lower eyelids, muted peach blush and soft rosy-beige lips. Keep the base makeup translucent and retain natural tonal variation around the eyes, nose and cheeks. Her skin is fair with a neutral-warm ivory and peach undertone. Visible skin includes the face, ears, neck, collarbones, a limited upper-chest area above the neckline, both shoulders, both arms and hands, and the thighs and knees exposed beneath the shorts. The waist, abdomen, back and main chest area remain covered. The skin should appear fine-grained, supple and lightly hydrated, as though the sunlit areas would feel gently warm and smooth while shaded areas retain delicate natural fine hair. Preserve mild color variation around the elbows and knees, small moles and subtle imperfections. Do not apply plastic smoothing. She wears a fitted warm-white ribbed sleeveless tank top with moderately wide straps and a modest scoop neckline. Add tiny pale-red lettering on the chest, visible ribbed knit texture and natural folds around the waist. The top fully covers the torso and remains opaque. Pair it with light-gray casual shorts, warm-white ribbed knee-high athletic socks and dusty gray-blue retro sneakers with white laces, pale soles and subtle wear creases. Add large thin silver hoop earrings, a pale round-faced wristwatch on one wrist and delicate gold bracelets on the other. Place the camera approximately 80 to 120 cm above the subject, tilted downward by around 35 to 45 degrees and shifted slightly toward her front-left. Use the perspective of a rear-facing smartphone 1x main camera, approximately 24 to 28 mm full-frame equivalent, at a close distance. Capture her full body from head to shoes. Position her mainly in the right and lower-middle sections of the frame, with the shoes close to the bottom edge. Let the chair form a strong diagonal through the composition. Allow a stone pillar and rough tree trunk to interrupt the left side of the image, while a woven gray basket partially enters from the lower-right corner. Preserve slight handheld tilt and natural perspective imbalance. The background is a real outdoor café terrace with warm beige-gray stone columns, pale square floor tiles, round wooden tables, additional wooden chairs, a gravel-filled tree bed, partially visible guests, a dark vertical utility fixture, metal railings, dense green foliage and cropped bags or furniture along the edges. Keep the environment slightly crowded and imperfect. Do not clean it into an empty studio or luxury hotel setting. Use mixed outdoor natural light. Warm sunlight enters from above and slightly front-left, grazing the hair, shoulders, forearms, white tank top and knees with localized bright highlights. Open sky and pale floor tiles provide soft reflected fill so the face remains evenly readable. Keep authentic occlusion shadows beneath the chin, inside the arms, behind the knees and around the chair back. No flash, no artificial rim light and no studio softbox. Maintain moderately deep focus so the subject is clearest but the tables, tiles, pillar and foliage remain recognizable. The finished image should feel like a friend spontaneously lifted a phone and captured a fleeting summer café moment. She had been chatting a moment earlier; now her fingers are moving toward a heart, and the next second she may laugh because the gesture did not align perfectly. Preserve mild sensor grain, slight highlight clipping, real skin texture, fabric folds, edge clutter and an imperfect social-media composition. Avoid mirror-selfie framing, low angles, perfect symmetry, exaggerated body proportions, sexualized styling, plastic skin, malformed hands, extreme bokeh, heavy HDR, watermarks and platform text.
