While this is still heavily wip I just wanted to post a shot of the direction I am taking the cliffs. The cliffs in the original environment were done with speed in mind, nothing more. It might sound crazy but the new direction will also give better performance overall too 
Keep in mind these are not areas I prettied up for screenshots, just took pictures of where the environment is at right now, long ways to go still
