Ночной уличный портрет со вспышкой в белом платье

Photorealistic night snapshot of [an adult woman with waist-length straight dark brown hair and wispy bangs], sitting shallowly on a horizontal metal sidewalk guardrail in a bustling shopping district at dusk. She is wearing [a white sleeveless fitted mini dress], [grey-brown knee-high high-heeled boots with double side buckles], and carries [a white quilted chain backpack]. Her body is angled slightly away while her upper torso twists back, calmly looking over her shoulder directly into the camera. Vertical full-body framing captured from a slightly low rear-diagonal angle, centered, keeping her boots completely within the frame down to the pavement. Illuminating front on-camera direct flash brightly highlights the white fabric, bare arms, legs, and metallic fence texture, while the distant urban background of shop signs, cars, and pedestrians melts into warm orange bokeh blur.
