Main subject: an exquisite transparent crystal square pyramid ornament, with multi-faceted cut facets on the crystal surface, showing a bright reflective effect. Scene: a miniature landscape of night Paris is simulated inside the crystal, with the Eiffel Tower lit with warm golden light in the center, flanked by typical Parisian-style off-white classical buildings dotted with warm yellow interior lights, miniature trees and small pedestrian models are arranged in the landscape, and the background is a dark blue gradient. Style: hyperrealistic miniature landscape style, combined with the craft texture of the crystal ornament, with a dreamy and romantic atmosphere. Color tone: taking cool dark blue as the background and the reflective tone of the crystal, matching with the warm yellow lights in the landscape to form a contrast between cold and warm, the overall tone is soft and harmonious. Light and shadow: the crystal surface reflects fine bright light, the lights of the internal landscape serve as the scene light source, creating a hazy night atmosphere, and the crystal ornament forms a soft reflection on the reflective flat base. Composition: using central composition, the crystal ornament is placed at the visual center of the画面, vertically combining upper and lower layers to highlight the details of the ornament subject and the internal landscape. Usage: as a Paris-themed crystal decorative ornament, suitable as a souvenir or a decorative craft for home desktop.
