ancient mechanical colossus 3d model

A vast underground cavern merging with an enchanted forest. A towering ancient mechanical colossus stands at the center, partially covered with glowing moss and tree roots. Bioluminescent energy lines spread across the rocky ground like organic circuits, flowing into a bright purple magical circle deep in the forest area. Tall trees surround the scene, their roots connected to the energy network. Soft fog, mystical atmosphere, cinematic lighting, a blend of ancient technology and natural magic in a realistic 3D style.
