A scene with Probuild and Terrain Tools

This is a simple terrain environment shaping scene. The corresponding locations are the same as those for the lifebuoys. P1

The scene is as shown in P2, where I tried to build the marble monument in P3 using Pro Builder. It just looks like the one in the picture :( , I don't have a good grasp of Pro Builder's curving skills.

The water part was borrowed from Terrain Tool and the water material.
