Ultra‑high‑resolution fractal-based 3D render of a symmetrical biomechanical str

$Ultra‑high‑resolution fractal-based 3D render of a symmetrical biomechanical structure resembling a spiked shell or alien artifact, composed of intricately folded and layered geometric patterns. The central form features petal-like lobes radiating from a recessed core, each adorned with sharp ridges, baroque spirals, and needle-point spines. The surface texture appears carved from weathered stone and polished bone, with complex organic-mechanical filigree spiraling along the forms like fossilized machinery. Lighting is dramatic and moody—single source from above, casting sharp shadows across deep crevices and emphasizing the radial symmetry and structural complexity. The background is softly vignetted in steel gray, providing contrast while enhancing the object’s three-dimensional volume and surreal presence. Fine details include micro-chiseling, subtle cracks, dust accumulation in recesses, and smooth wear on protrusions—suggesting age, erosion, and alien craftsmanship. Rendered with ray-traced global illumination, ambient occlusion, and sub-surface scattering in layered materials. Color palette limited to bone white, dusty beige, oxidized brass, and charcoal black, with soft specular sheen. Visual tone is mysterious, cryptic, and biomechanical—blending ancient ornamentation with futuristic decay. Perfect for surrealist concept art, alien ruins, dark sci-fi structures, or symbolic symmetrical designs.
