This is a highly detailed CGI illustration depicting a futuristic, sprawling cityscape set in a lush, verdant valley. The city is built into the side of a rocky cliff, with numerous interconnected structures made of sleek, metallic materials, including shiny, reflective surfaces and sharp, angular lines. The buildings are densely packed, with a mix of cylindrical, spherical, and rectangular shapes, all bathed in a warm, orange glow from internal lighting. In the foreground, a serene river flows through the valley, with a small boat navigating its calm waters. The riverbank is lined with wooden structures, some of which appear to be shops or market stalls, with a few people milling about. To the left, a tall, spire-like tower rises into the sky, topped with a glowing orb. The background reveals a vast, blue sky dotted with fluffy white clouds. In the distance, a large, white planetoid floats, adding to the otherworldly feel of the scene. The cityscape is bathed in a golden hour light, casting long shadows and highlighting the intricate details of the architecture. The overall ambiance is a blend of futuristic technology and natural beauty, creating a harmonious, almost utopian setting
