Compose a photorealistic rendering of a futuristic habitat. The scene should feature several large bio-domes, constructed with transparent materials that reveal lush, verdant ecosystems within. The setting is an exoplanet, with unknown vegetation growing around it and a mountainous area highlighted by rocky surfaces in the back. These domes should be connected by sleek, organic walkways, with waterways that meander around them, reflecting the serene environment. The structures should be nestled in a tranquil landscape of gentle hills and calm waters, with the soft light of dawn or dusk casting a warm glow and creating a peaceful, atmospheric setting. In the distance, majestic mountains add to the natural grandeur. The image should capture the essence of a visionary, eco-friendly future, looking as if it were a still taken from an inspiring scene in an environmental sci-fi movie. --ar 2:3
