This tree is from a concept of Dreamworks find on their book. I started by Zsphere to create all the tree and have the perfect shape of it. Then the fun began, I sculpted it in dynamesh.

The goal was to start by a concept art, we could choose a character or an environement, and to do it in 3D. I have chosen Zbrush because the Zsphere was an incredible tool to create a tree character quickly.
