rock cliff terrarium 3d model

Create a 3D model, a slightly concave curved back panel insert for a cylindrical glass tube terrarium. The front is a realistic stratified rock cliff wall with layered stone, cracks, and natural erosion. Include an arched cave entrance near the bottom with a shallow interior. Add rock shelves/ledges on the sides with organic overhangs. Place a small stone watchtower/guard post (medieval ruin style) on one ledge. Integrate an open water channel starting near the top edge and running down to a bottom outlet, designed to guide real water into 2–3 stepped waterfall cascades with small basins and side walls to keep the flow contained. contain everything within cylinder. dont generate water itself, just path for it. make it realistic.
