薄暗い大聖堂に浮かぶ虹色のシャボン玉

Masterpiece. Best quality. Ultra detailed. Beautiful composition. Cinematic. Epic. Dramatic. Attention-grabbing. An iridescent soap bubble, caught mid-flight within a dark, cavernous cathedral. Rainbow refractions dance across the ancient stone architecture, casting prismatic light patterns that shift and change with every subtle movement of the bubble. The prompt emphasizes hyperrealism in the bubble's delicate surface and the cathedral's texture, with a stylistic nod to Baroque tenebrism for dramatic contrast between light and shadow.
