ภาพพอร์ตเทรตในสวนสาธารณะใต้แสงแดดข้างต้นไม้

Photorealistic vertical portrait of [a young East Asian woman] sitting on lush green grass in a sunny park, leaning beside the thick trunk of a large tree on the right side of the frame. She has [long straight black hair], fair skin, delicate natural makeup, and a calm, slight smile looking directly at the camera over her shoulder. She wears [a flowing white halter sundress with an open back and thin tie straps], its translucent layered skirt spreading softly across the grass. Her body is in profile facing left with knees bent, hands resting in her lap while holding [a black smartphone]. Background shows a sunlit park with exactly 3 visible small tree trunks in the distance, dense leafy shrubs, dappled sunlight, and soft shadows beneath the canopy. Realistic smartphone photography aesthetics, natural summer daylight, fine texture in grass and tree bark, gentle backlighting from upper left, shallow to medium depth of field, candid elegant composition. No text, watermarks, extra people, or artificial studio lighting.
