Métropole Flottante Futuriste Sous un Anneau Cosmique

A vertical view of a futuristic metropolis floating gracefully above an endless sea of dense, rolling dark grey clouds at twilight. The sprawling city skyline features towering skyscrapers with glowing windows casting warm amber and orange lights onto the urban landscape below. Dominating the upper portion of the frame is a magnificent cosmic ring nebula composed of [vibrant purples, deep blues, and brilliant warm golden hues], sprinkled with countless twinkling stars and distant galaxies across the deep black sky. Balanced composition with the dark cloud layer in the lower foreground grounding the scene, contrasting with the radiant celestial phenomenon above. Surreal, ethereal lighting blending warm city illumination with cosmic luminescence. Detailed textures of voluminous clouds, sleek glass and steel towers, and stellar dust.
