浮遊する水晶の天空城を守る玉虫色のドラゴン

A colossal, iridescent dragon coiled around a floating, crystalline castle suspended in a twilight sky. Swirls of nebulae and distant stars form the backdrop. The scene is rendered with the fluid brushstrokes of impressionism, with touches of surrealist distortion and dramatic, cinematic lighting that casts long, ethereal shadows.
