fantasy base map 3d model

Create a highly detailed 3D isometric fantasy strategy map base inspired by the reference image. Generate only the terrain and planning layout: vast grassy valley, rocky cliffs, rivers, small waterfalls, bridges, forests, mountain background, cinematic golden sunset lighting, mist, stone paths, circular plazas, radial roads, rectangular and circular empty building plots, low stone borders, terraces and foundation markings. Style: premium medieval fantasy kingdom, realistic-stylized, blue/gold mood, game-ready environment, clean modular layout for placing buildings later. No castles, no houses, no towers, no temples, no walls with buildings, no characters, no text, no UI, no logos. Optimized 3D asset, PBR textures, high detail but usable in Blender, export as GLB.
