(masterpiece:1.1), (ultra-detailed), (best quality), macro, 8 K, cinematic lighting, A close-up macro scene of a swallowtail butterfly resting on a rugged sandstone cliff at golden hour. Its wings are half-open and shimmer like a galaxy — sapphire blue, teal, magenta, and amber streaks, dusted with fine glittering specks. Bold black veins trace the wings; the lower edge shows vivid orange-red teardrop spots. Back-lit by warm sunset light that pours through forest haze, forming soft volumetric rays and a golden rim-light along every wing edge. Tiny glowing butterflies drift in the bokeh background; floating dust motes catch the light. Photorealistic wing-scale texture, crisp focus on the butterfly and rock grain, dreamy blurred backdrop, fantasy yet natural atmosphere.
