Very beautiful, everyone can tell that.
But the concept seems a bit dull eh?
Texture is really intriguing but the landscape itself leaves me a bit unsatisfied. Just chunks of mesas repeating here and there...
You could have done better with that.
Let's have a play, be that as it may...
EDITED
I think the textures are awesome,really good.
The detail tex are great the textures look detailed but not messy and the units are clearly visible on them.
+1 on Sir's opinion about the concept though.
