ancient gnarled tree 3d model

A cinematic ultra-realistic full shot of a monstrously ancient, leafless giant oak tree. Its trunks are uniquely formed by countless gnarled, intertwining roots and thick, twisted boughs, creating a complex, sprawling skeletal structure that defies gravity. The bark is texture-rich, grey, weathered, and deeply fissured. The base is an immense, sprawling network of exposed, ancient roots on dry ground, providing dramatic scale (add a tiny human silhouetted figure at the base for scale comparison). Dark grey gradient studio background, dramatic volumetric lighting highlighting the intricate details of the wood grain, 8k resolution, photorealistic masterpiece, biological architecture aesthetic.
