The Layers Of A World

I made the three layers of a world. The top layer is the layer we all live on. It includes three windmills, a mountain, and a mine. Just below that layer is a giant cavern with a river going through it. It has stalactites coming from the ceiling of the cavern, a tiny cave entrance, and a little boat who seems to be lost. The bottom layer is all lava, it has a skull and a giant rib cage. It also has lava dripping from the ceiling. This is a model set and is not meant for playing. I think this would be a great set because it is a set that is interesting to look at and has a lot of cool little features.
