It's really late, but I wanted to check in. I'm glad you liked my insights, but I just realized something. It looks like you're using a Mercator projection of the Earth underneath the map of your world. That doesn't project onto a sphere properly using the software I used. See if you can find an equirectangular projection and slide that underneath and that will give you a better comparison of where your land masses would be when projected on a sphere.
More tomorrow.
