Floating Islands v1

Hey guys,
I wanted to show you an early attempt at terraforming I did a while ago. I made these with MCedit and I made the tops flat because I want to build on them later and I would prefer to have a little more room to work with.
I also made the bottom level under the islands have some floating debris to give a sort of antigravity/suspension feel.
I dont' yet know what I want to add here, but there are some experimental builds I added on top of some of the islands.
