A whimsical floating cosmic greenhouse depicted in delicate art nouveau style, drifting gently between luminous constellations. Curving organic structures crafted from polished bronze and crystal intertwine and support bioluminescent plant life, glowing in soothing pastel hues. Small winged caretakers, reminiscent of vintage fairy tale illustrations, gracefully tend to plants while gliding between intricately patterned stained-glass windows that softly filter starlight from distant galaxies. Rendered with flowing lines, ornate botanical flourishes, gentle airbrush shading, and a dreamy mid-20th-century retro-futurist palette of sage greens, coppery golds, lavender, and muted cosmic blues. <lora:retro-futurist-cosmic-surrealism-flux:0.75>
