☆ Battle arena Update - Happiest day of my life. I made Curves in Maya ☆

I worked over my idea of having my arena in a forest and decided that I want to have something more like a floating rock with trees and platforms on it.

I want to model huge rocks with swirls on them and have my arena have a lot of round shapes as shown below.
