Prompt: a celestial creature inspired by the cosmos, featuring intricate patterns reminiscent of galaxies, nebulae, and cosmic dust. Design a creature with iridescent, star-like markings on its sleek, extraterrestrial body. Incorporate cosmic elements such as ethereal wings that resemble solar flares and tail tendrils that evoke the trails of shooting stars. The creature should emanate a soft, cosmic glow and be surrounded by a cosmic aura. Envision it in a cosmic landscape, perhaps floating amidst constellations or cosmic clouds. Use a cosmic color palette that includes deep blues, purples, and cosmic rays of vibrant hues to convey a sense of the vastness of space.
