I didn't have much time today, so I decided to gradually update the graphics rather than implement new features. Most of this stuff are simple blender models, with minimal effort. (Most of the work was getting them to fit into the frame). The new grass texture is actually a photo of grass, blurred, picked, and posterized into unrecognizability.
I still don't like the new citizen's eyes. I still fail to strike the balance between the eyes being invisible, and therefore creepy, or to big and bright, and therefore creepy. I think the citizens should be somewhat sympathetic, to motivate the player more, and increase the immersion. I guess I will just use my experience with making citizens creepy on the zombies.
In terms of programming, a fixed a bug where building could be built on top of each other, and also added a fix so you can't place citizens on top of building or each other. This is to prevent a strategy where you part all your citizens on top of each other on a spike pit, and do easy double damage, or even put multiple spike pits on top of each other.
