I had been recently exposed to Adventure Time by my kids, the influences are clear. This programmer's art so go easy on me. Also there is very little detail. All materials are solid colors. Only two instanced objects (a tree and a stump) but I think it works for the most part.
You can read a guide on how this was built here. It served as an example of how to create a biome from scratch in Voxel Studio. We will probably expand this project to cover other topics like voxel instances and runtime extensions.
