32k photo-realistic, high-definition, abstract landscape of a city on a different planet. The towering architecture is crafted from a translucent, silver-blue crystal, infused with ethereal light that pulsates through its veins. The city crumbles and decays in places, overtaken by moss and vines that create pockets of verdant lushness amidst the futuristic metropolis. The sky overhead is a deep shade of purple, with a row of holographic planets suspended high above the cityscape. The style is reminiscent of fantastical world-building, with intricate details and a sense of grandeur and decay. (Add other abstract landscapes with sunsets, nebulae, and alien biomes in various color palettes).
