PROMPT:
Create a cosmic reverie image that embodies the essence of celestial wonder, where vibrant hues of turquoise, emerald, and amber dance across the canvas, evoking an ethereal sense of mystique. A majestic, glowing nebula occupies the central focus, its luminous tendrils swirling in harmony with stardust and glittering, diamond-like particles. Incorporate a subtle, iridescent sheen to imbue the entire scene with an aura of shimmering, otherworldly beauty. The atmosphere should be filled with an air of tranquility, as if the cosmos itself is in a state of serene reverie. Use photorealistic techniques to craft an image that is both mesmerizing and hauntingly beautiful.
