"prompt": "A photorealistic portrait of a stylish young woman sitting at an outdoor Parisian café with red woven bistro chairs and circular white tables. She has long, smooth, straight, honey-blonde hair, parted neatly in the middle. She is wearing a classic black beret, a crisp white button-up shirt, and a dark blue tie with diagonal gold stripes. Over her shirt, she wears a slightly oversized black leather jacket. She accessorizes with pearl and gold hoop earrings on one ear. Her makeup features sharp, winged eyeliner, defined eyebrows, and a natural nude lip color, giving her a chic, confident look. The scene captures a soft afternoon ambient light, with clear reflections on the glass window behind her. Through the window, vintage-style golden lettering that reads \"ROYH...\" is visible, partially cut off due to her posture. In the background, a Parisian street is subtly mirrored in the glass. The camera angle is eye-level, front-facing and slightly to the right, creating a natural, elegant composition. The color palette is warm and clean with a touch of Parisian café ambience. Extremely detailed, 8k resolution, sharp focus, shallow depth of field, photorealistic style, natural lighting, cinematic atmosphere, high fashion editorial aesthetic."
