Ancien dieu cosmique descendant sur une ville futuriste dans une nébuleuse

A colossal ancient god, cloaked in starlight, descends from a celestial realm towards a futuristic city built on swirling nebulae. The architecture is a blend of art deco and bioluminescent alien designs, with sleek, crystalline skyscrapers piercing the cosmic dust. Beams of divine energy emanate from the god's form, casting dramatic, high-contrast shadows across the cityscape. The style is a fusion of epic mythological concept art and surrealist digital painting, reminiscent of the works of H.R. Giger and Zdzisław Beksiński, with a palette dominated by deep violets, electric blues, and molten golds.
