But the double thread wasn't.
I advise you to remove it.
Anywho, let's see...
Blizzard trees = no, use custom tree models;
Blizzard cliffs = no, shape the ground manually;
Theme? I don't see any;
Now when you start a terrain you need to strive for three main things:
- Originality
- Theme
- Doodad placement
Your terrain is generic, mediocre. For a terrain to be recognized and referred to as a piece of art, it has to be outstanding, out of the ordinary.
Remember this.
