Mini Zoo Chapter 7

Okay, it is a good idea, but this doesn't look realistic.
First, the houses. Change the scaling, I think that they should look at least a little different. Also, one of them has grass over the doors.
Second, you could improve the archways. Add some horizontal columns or more archways on the existing ones.
Third, the forest on the right. It looks like... I don't know, but it doesn't look like a forest. Add plants, logs and rocks.
Fourth, the Zoo (or at least I think it is the Zoo). The walls are too low, you could use the same model of fence doodad that you used in the center. You have giant mushrooms, flowers and other plants growing out of solid rock? And the ground beneath Kobolds burns and has lava cracks?
Come on, seriously. I think your campaign is really great, but hire a terrainer.
