Diorama isométrique en cube de ruines antiques couvertes de bambou

Isometric 3/4 view of a photorealistic architectural diorama cube floating in a neutral void with light atmospheric fog for depth. The cube features a cutaway front wall revealing the interior. On top: ancient oriental ruins with moss-covered stone, cracked columns, and tall bamboo stalks with delicate leaves showing subsurface scattering, a few fallen leaves scattered naturally. A spiral stone staircase winds from the bamboo-covered rooftop down into the exposed interior ruins, where warm light glows from small windows. An ancient forgotten lantern rests on one step, and weathered inscriptions are visible on crumbling walls. The cube's side faces display detailed geological strata: dark humus → reddish clay → gravel → bedrock → subtle quartz veins catching light. Dramatic side lighting with soft rim light highlights the bamboo and textures; subtle god rays with floating dust particles add atmosphere. Earthy neutral palette: bamboo green, stone gray, soil brown, accented by golden-hour warmth. Unreal Engine 5 vibe: Nanite-level micro-details on stone and soil, Lumen global illumination, realistic ambient occlusion, high-contrast cinematic grading, 8k resolution, photorealistic, shallow depth of field focusing on the diorama.--no people, animals, text, watermark
