coin bas-relief 3d model

Create a circular coin-style bas-relief model from the provided image. Keep the original composition exactly the same. Do not add or remove any elements. Preserve all existing mountains, moon, clouds, and frame details. Apply shallow embossing depth similar to a realistic minted coin. Slightly increase relief height only for better visibility. Keep surface clean, balanced, and realistic metal engraving style. Maintain circular coin border. Ensure even depth distribution across the design. Avoid deep extrusion or exaggerated 3D protrusion. Result should look like a real engraved metal coin bas-relief.Avoid strong depth exaggeration. Keep relief subtle and shallow. Maintain coin-like engraving depth consistency. No high extrusion.
