it looks average. Not a particularrly great terrain.
here are a few things to improve upon :
1) the background has abnormally huge stars. If you instead use the " Lightning bolt prjectile" ( the Far Seer's attack ) and use that projectile as the star model, and then shrink it to a default size of .2 , you get the perfect twinkling star. Instead of using those glows, use the tecknique i described instead
2) the Rock spam looks very ugly. Covering it with fog would be a good idea, or instead use the height variation ' raise ' and make mountains that way.
Not only that, but the fog could be instead of :
x : 4000
Y : 5000
instead use fog that is :
x: 0
Y : 4000
you will get better, more realistic terrain using that kind of fog values.
other then that the structure, camera angle and the doodad use in the forground was pretty good. keeep workling on it
