Thanks for the comments guys!

There have been a couple notes about the icons. As I mentioned in one of the first few points, they were copyright free online. I didn't make them and I don't know how to make them . That's why I couldn't increase the line thickness and why you see repetition.

There were a limited number of icons, and I ended up using all or almost all of them. To solve this problem, I thought the Tokyo icon really lended itself to depicting a very uniform state. When I made the last nation I used what I believe to be the second-best icon for this purpose. I do think having green be uniform works well, as green isn't all about individual expression and individual freedoms! Red, not as much.

With so little time left, I don't think it's within my abilities to learn how to make icons and redo them all. My options are:
1) Keep it as is.
2) Diversify the red cities, but using the same icons as I used for purple up top.
All, please let me know which of the two options you'd rather see. I shall bow to the wisdom of the commenters
