A grand celestial greenhouse suspended serenely in deep cosmic space, its curving glass architecture intricately framed by gleaming bronze filigree and iridescent crystal supports. Inside, lush gardens filled with bioluminescent plants grow in floating soil spheres and translucent containers, their roots extending outward into open nebula clouds, absorbing starlight to survive. Graceful gardeners dressed in ornate cosmic-patterned robes drift weightlessly between spiraling green pathways and fountains of flowing, luminous liquid suspended in gentle, gravity-free arcs. Outside the greenhouse's transparent dome, mythical space creatures reminiscent of deep-sea life swirl gracefully, emitting faint bursts of ethereal glow. Render the visual using expansive cinematic composition, gentle airbrush textures, and warm copper tones contrasting vibrantly with deep emerald greens, purples, and muted cosmic blues, all executed in the nostalgic surrealistic style evocative of mid-20th-century science-fiction artistry. <lora:retro-futurist-cosmic-surrealism-flux:0.75>
