Create an image of a futuristic cityscape at dawn, where towering skyscrapers are covered in lush vertical gardens and interconnected by sleek, transparent skybridges. The buildings' facades are a mix of gleaming glass and organic materials, reflecting the soft golden light of the rising sun. In the foreground, a wide, bustling avenue is lined with floating market stalls selling exotic, bio-engineered plants and futuristic tech gadgets. People in stylish, avant-garde attire stroll through the market, some accompanied by robotic pets. The air is filled with the hum of drones delivering packages and the soft chatter of a multicultural crowd. At the center of the avenue stands a majestic, ancient tree with bioluminescent leaves, its roots embedded in a transparent platform suspended above a crystal-clear pool of water. This tree serves as a symbol of the city's harmonious blend of technology and nature. Above the city, sleek, silent hovercrafts glide through the sky, leaving trails of light that slowly fade. The horizon is dotted with floating wind turbines and solar panels, capturing the sun's energy to power the city. Colors are vibrant and diverse, with the greens of the gardens contrasting against the metallic blues and silvers of the buildings. The overall composition exudes a sense of innovation and sustainability, painting a picture of a utopian future where technology and nature coexist in perfect harmony.
