Floating castle city above clouds at sunset with hot air balloons

Digital 3D rendering depicting elevated fantasy architecture suspended above dense cloud formations. Multiple castle-like structures cluster on a central elevated plateau with illuminated towers and warm golden-orange ambient lighting. Four hot air balloons positioned at various heights throughout midground. Sunset gradient dominates: orange-yellow sky at center transitioning through pink and purple hues. Volumetric clouds with precise shadow modeling beneath landmass. Rock formations visible on adjacent islands. Dramatic backlighting from sun positioned behind architecture creates volumetric light rays. Color grading emphasizes warm temperature palette with saturation concentrated in central illuminated area.
