I would suggest making the terrain in the first picture of the last group of images more varied in height the grass looks flat, it is rarely like that in the WoW Trisfal Glades. Maybe ad some rocks and grass doodads too.
That's more of a story issue not a terrain issue though. I didn't know why humans were there. There are some human camps in Trisfal Glades. Most of them Scarlet Crusaders. There is also that farm with human villagers being overlooked by that tower right as you get out of Deathknell.
Some of them have been updated! I eagerly wait for your opinions!1st pic: Nice, i like how u made the cliffs.
2nd pic: A bit empty, add some more environmental doodads.
3rd pic: Looks cool, the only thing that i don't like are those statues and potted plants, they don't fit at all. Try to find some of higher quality, or remove them and add something else.
4th pic: Dat grids. It isn't bad at all, but add more life to it.
Overall a good terrain, like the way u do the buildings! Keep it up!
