Autômato celeste de engrenagens em um mundo alienígena desolado

A celestial clockwork automaton, its gears intricately designed and its metallic surface exhibiting a fragile beauty, stands on a desolate, alien planet. Nebulae in vibrant hues paint the night sky, creating a sense of cosmic melancholy. The style is a fusion of steampunk aesthetics and ethereal fantasy art, with a focus on intricate mechanical details and atmospheric lighting. Imagine the detailed concept art of H.R. Giger meets the luminous landscapes of Roger Dean.
