Ancient dragon on alien mesa beneath swirling cosmic nebula

A lone, ancient dragon with scales like shattered obsidian sits atop a desolate, alien mesa under a swirling nebula. Its eyes glow with cosmic dust, and the vast, empty landscape stretches to a horizon where twin moons hang. The scene is rendered in the style of a melancholic oil painting, with deep, brooding colors and an intricately detailed, desolate atmosphere. Inspired by the works of Zdzisław Beksiński and H.R. Giger.
