Unity Terrain Explorations, Part 2

After getting the initial topography and texturing the way I want it, it's time to add trees, grass, a sky and water! By now the procedural node map is getting a bit crazy -- thankfully this is about as big as it needs to get for this experimental environment.

The challenge from here is to see what I can do to make this prettier and more lively. The landscape is believable enough as-is, but it's motionless and feels pretty unpolished, and flying around in first person isn't terribly charming... <.<
