masterpiece, An oil painting of an alien planet, A distant exoplanet glows with ethereal beauty. Sweeping purple auroras dance across the night sky, illuminating crystalline spires of an alien metropolis below. Rings of shimmering turquoise dust encircle the planet, casting a soft, otherworldly light on the landscape. In the foreground, bioluminescent flora pulse with gentle rhythms, their colors shifting from deep indigo to vibrant teal.
