This is cool man!
I’m a big fan of how this guy makes his terrain textures. https://youtu.be/6X4BfUrFdEI?t=3m15s
Another thing you could possibly do is add some ambient occlusion. I think the way I used to do it is probably dated now….there’s probably a node for it these days. I used to bake a diffuse and an AO map and in photoshop I would merge the AO into the diffuse on a separate layer. Then reduce the AO layer to something like 15% opacity. I felt it gave the terrain a nice punch.
Anything you can do to break up the tiling in your texture would be a plus.
Really cool so far though. Did you use the terrain add-on in Blender?
