Ethereal Starlight Dragon Rising From A Cosmic Nebula

A single, ethereal dragon made of starlight and mist emerging from a magical, glowing nebula that resembles a castle in silhouette. The nebula's colors are vivid and dreamlike, swirling with cosmic dust. The overall effect is one of cosmic wonder and serene magic. This image should be a masterpiece, inspired by the cosmic art of Chesley Bonestell and the fantasy illustrations of Yoshitaka Amano, with a focus on luminosity and atmospheric, cinematic lighting.
