I think the lemur is better. Baobab trees grow in Africa and they have been found as far away as planet B612. Lemurs only live in Madagascar.
Maybe it's because I've been watching
The Penguins of Madagascar too much, though.
As for other ideas, Tibet will have an endless knot as its symbol, along with a color change to saffron (AKA the color of the robes Buddhist monks wear).
For the Seminole, I'll probably go with a Tomahawk (Tomahawk Chop anyone?). I'll change their colors to Garnet and Gold to go along with it.
Gran Colombia will likewise get a color change to Burgundy and White (like the Venezuelan uniforms.)
Finland and Buryat will likely switch colors, mainly because I have a Finnish button already made with the Buryat main color. It's the same flag from Civ Gold, but inverted.
Polynesia's symbol baffles me. Why the Kanak flag? The Kanaks are Melanesian, not Polynesian. I think either the symbol on
this Hawaiian flag or a tiki mask would be better.
Mexico's flag will be changed to Rhye's decal of the coat of arms of Mexico.
The civs from Colonization will all likely have their original flags, with the exception of the Arawaks. I've never liked the turtle for them. The Taino Sun is a much better symbol for them.
For Ireland, do you prefer the harp or a shamrock?
Etruscans... I don't get the lion. Looks cool, but thinking of many symbols I think I'll give them a chimera (they're known for making a famous Chimera statue).
I'm currently deciding between two symbols for South Africa:
the symbol in their coat of arms or
the flag of Cape Town
The Austrians will have an edelweiss as their symbol.
Mutapa is definitely getting the Zimbabwe bird. Congo's symbol will be changed to the leopard's head from their coat of arms.
