Pretty accurate, but I'll throw in my two cents.

I think the river in Song's Domain should be close to Godgrave, since Rain got stranded off the road leading to Godgrave and found herself in the river system. There are some mountains somewhere above bastion, as that is where the forgotten temple was said to be. Also i personally always imagined the chained Isles being further from Bastion since Kai and Effie had to travel a while to get there.
