Twilight Park Stair Portrait

Create a cinematic hyper-realistic portrait of a character_age_and_gender sitting casually on weathered stone stairs in a quiet park at twilight, beside an old glowing lamp post. She has a soft natural smile, relaxed posture, arms resting on her knees, and slightly messy dark hair styled in a long side braid. Outfit includes exactly 5 visible pieces: a shirt_color_and_style, black cargo pants, white sneakers, a black smartwatch on one wrist, and minimal natural makeup. Compose her seated on the right side of the frame, with the vintage lamp post on the left emitting warm yellow light; add two small blurred park lights in the background. Use shallow depth of field, soft bokeh trees, warm dusk ambience, realistic skin texture, natural proportions, and cinematic color grading. The stone staircase should look aged, stained, and textured, with a curved side wall leading diagonally through the composition. Shot on a full-frame camera with an 85mm lens look, f/1.8 depth of field, balanced twilight exposure, ultra-detailed photorealism, no text, no watermark.
