Une sorcière éthérée prépare une potion magique dans une serre gothique baignée de clair de lune

A breathtaking, ultra-detailed masterclass artwork of an elegant, ethereal witch brewing magic inside a moonlit gothic greenhouse. The witch wears a deep midnight-blue velvet gown embroidered with glowing gold filigree and a pointed wide-brimmed velvet hat. In front of her, a heavy ornate iron cauldron overflows with swirling bioluminescent turquoise and magenta magical vapors, sending shimmering glowing droplets into the air. Floating around her are ancient glowing spellbooks, potion vials with golden stoppers, and bioluminescent mushrooms. Dramatic volumetric moonlight filters through stained-glass windows, casting striking rim light.
