Hey Frank and clan! Just thought I'd say I'm really appreciating the level of commitment and detail you guys are showing, it a really fine world you have here which I see is still very much growing! Congratulations on finishing your rivers, I'll be following this to see how you plan on placing you're cultures and ethnicities. I'm an anthropology buff who is already a participant in another collab project and if I can chime in when I come back here I'd love to make some suggestions based on what I've learned. I'll say this much, the migration patterns on this world are going to be pretty different to old earth. The continents are much closer with they're being a very limited distinction between 'Old' and 'New' worlds and many of your coastal regions are breeding grounds for expansionist maritime cultures so expect a lot of intermixing early one and a more multi-polar world than our RW.
The geography here is some of the very best I've seen on a fictional world, you really have pushed the bar higher with this level of detail and your climates and environments seem just about right for the arrangement of landmasses you have. There really is nothing more to say on this.
Carry on doing God's work: World-building.
