A full body shot from a slightly low-angle, three-quarter view of an elegant young female detective standing in a dynamic diagonal composition within a grand European mansion's entrance hall. She is a refined young lady with long, silky dark brown hair, soft straight bangs, and delicate pointed elf ears; she wears small round glasses and possesses sparkling heterochromatic eyes—one soft violet and one warm golden—with a slightly smug, confident smile. Her aristocratic attire consists of a fitted dark navy long coat with ornate gold buttons and a decorative belt over a luxurious dress with a high lace collar, layered elegant skirt with subtle embroidery, lace knee-high socks, and dark brown heeled shoes. She holds an antique silver pocket watch in one hand while her other hand is raised in a confident detective salute near her forehead. The background features a polished wooden floor, a grand chandelier, and an ornate wooden staircase under tall arched windows. The scene is bathed in warm golden light and soft afternoon rays with floating dust particles, utilizing a shojo manga style with delicate lineart,soft focus, and dreamy sparkle effects.
