Settlers of Catan Native American Theme

I liked some of the other custom civilizations that people have made for catan on here, like the chinese and the roman etc. But I could only find 5 custom civs, and I want to make a 6 player board so I came up with a Native American theme.

The settlement is a wigwam, the city is a teepee, and the roads are trails through the woods. I did borrow the wigwam model, otherwise created the models myself

This thing was made with Tinkercad. Edit
