Create a photorealistic 3D scene featuring bold, oversized metallic letters A F D in the foreground. The letters are weathered, rusted steel with a rugged, chipped surface and strong beveled edges. They loom over cracked, dry ground with subtle wet reflections. Behind them, a dramatic sky swirls with dark, menacing clouds, illuminated by a fiery sunset glow that peeks through the clouds and outlines the letters with a bright rim. The composition is cinematic with high contrast, rich textures, deep shadows, and a strong sense of scale and depth.
