Example Architecture Prompt:
A contemporary landscape architecture scene centered on a smooth metallic statue shaped like a fluid, flowing form. The statue has a polished chrome surface with continuous liquid-like curves, rounded edges, and reflective highlights, positioned on a circular stone plinth in the center of a refined public garden. Surrounding it are clean paved walkways, low ornamental grasses, sculpted shrubs, native flowering plants, and evenly spaced small trees. Modern stone seating borders the planting beds. Natural daylight from the upper left creates soft shadows across the paving and crisp reflections on the metal sculpture. Wide eye-level composition, with the statue as the central focal point and the landscape design clearly visible around

Example Architecture Prompt:
Replace only the central art piece with a new smooth metallic sculpture shaped like a suspended liquid ribbon. The new sculpture should have polished chrome material, seamless rounded surfaces, and flowing organic curves that twist upward from the base like a frozen stream of metal. Keep the same scale, placement, circular plinth, surrounding landscape, paving, trees, lighting, shadows, and camera angle unchanged. The replacement sculpture should look physically installed in the plaza, with realistic reflections, contact shadows, and no visible seams or construction joints.
