low poly island 3d model

Isometric game asset view of a floating island terrain, low poly style, magical forest theme "Lumina Forest". The terrain features rolling hills, a central elevated plateau, and a glowing cyan river cutting through the land. Distinct biomes: snowy white peaks in the north, dark charred volcanic crater in the south, and dark lush green grass in the center. NO VEGETATION, NO TREES, NO ROCKS, NO BUILDINGS. Purely bare ground topography and water. Soft magical lighting, ambient occlusion, 3D render, blender style, clean smooth edges.
