城墙--可以更加厚重，而不是薄薄的一层，

人物--可以调整比例大小，人物太大看起来不好看；，

城市绿化--可以建设的更美，更多漂亮的建筑和绿色植物。尽量做真实些漂亮些，现在效果图看上去没有城市规划的感觉，很乱，不美。

I agree with them, their points were:

1) Make the city walls a little thicker

2) Make the character models of humans a little smaller, they look too big in relation to the world. 

3) Make the cities a bit more defined architectureally, and greener with more trees and plants. He wants something more realistic.
