Week 1 Environment Reference and Proxies

My intentions for the environment are to use roots as elevated pools of water that lead from the smooth cave walls where water has eroded and smoothed out the rocks and work my way up to a petrified tree that gets greener as it reaches the top with vibrant foliage.  The surrounding structures will be shaped into roots which separate the surrounding water into distinct pools of water.

 The surrounding cave wall will be eroded into a smooth structure with more angular, chunky rocks coming together at the top to make a hole in the above cave to let light in to nourish the tree.

After a pass in Zbrush I'm hoping these rocks will come together as building blocks for the non-eroded rocks that surround the cave walls.  I imagine I'll have to make more as time goes on, but a lot of my work will be able to be saved after the sculpt by using some of Zbrush's more advanced transform abilities to create arched rocks or even circularize some of my existing rocks or groups of rocks.
