Quel'Thalas

I decided to do a random terarin of Eversong and the Ghostlands. So, here they are!

Screenshot 1- Acolytes doing something sinister, as usual.
Screenshot 2- A random canyon!
Screenshot 3- Ghosts haunting some ruins.
Screenshot 4- A Blood Mage being escorted by a guard of Swordsman.
Screenshot 5- A Ranger and co. guarding a statue.
Screenshot 6- a haunted and destroyed village.

I'm going to take a shot in the dark and guess this is your first terrain. There are many things wrong with the terrain but for starters...
- Lack of ground level variation (other than making mounds, the whole terrain is flatter than Celine Dion.)
- Clashing elements (SS6)

SS1 is not too bad but it it lacks the level variation to make it look natural, and I don't really feel anything from it.

There are damn many floating rocks in screenshot #2

And trees.
This universe must not have very strong gravity.

It is quel'thalas after all. everything floats there. hehehe

First one is the best. But you really need to add more tileset variation to your terrain. Looks way too plain and the less variation there is, the more empty it looks. Add more environment doodads such as shrubs and rocks and tint the color of river rushes to a darker color and use them too.
