Create a high-resolution image of a utopian city where advanced technology and nature are perfectly integrated. The cityscape should feature sleek, futuristic buildings with green rooftops and vertical gardens. There should be flying cars and drones, clean energy sources like solar panels and wind turbines, and people enjoying a vibrant, healthy lifestyle. The environment should be lush with trees, flowers, and clear water bodies, all under a bright, clear sky. The overall atmosphere should be peaceful, vibrant, and full of life
