In this school project I made a 3D cube world.

There were four restrictions; the setting needed to be in the sky, the theme was paradise, the era was an alternate reality and a must have object was a river.

Long ago an old, and now, lost magic had forced square pillars out of the ground and high into the sky. On this particular pillar there was a small sprout growing. Years later with the minuscule amount of rain water, it grew on the magic infused ground into a sapling. But it was no longer satisfied and wanted more water to grow into an adult tree. It pulled water from the sky around it, making a floating river around the pillar. Now it lives as a mature tree with its roots dangling into its own river. 

Because I can't picture a paradise with people/society I wanted nature to be a focal point in this project. I ended up with the idea of a tree that grew on top of a pillar in the sky.

A quick block-out I made in 3D, this also made me realize the design was too long and needed to be a bit more compact.
