A hyperrealistic architectural visualization of a futuristic eco-city built on the side of a cliff overlooking a vibrant turquoise ocean. Sleek, organic structures blend seamlessly with the natural rock formations, covered in lush vertical gardens. The city is powered by solar panels and wind turbines, integrated into the design. The scene is bathed in the warm, golden light of sunset, creating a sense of serenity and harmony. A wide-angle shot captures the scale and grandeur of the city, with the camera positioned slightly above, looking down. The color palette is dominated by natural greens, blues, and browns, with accents of metallic silver and glass. 4k resolution, a true architectural masterpiece.
