This... is an amazing idea. At that scale and with those images, you're on a roll.
I have a few questions/suggestions.
Where on the continent does the sun rise through the middle of the world? I don't see anywhere that seems to look like that. For that matter, where does it set?
How do seasons work? Why is that little bit up top white? This isn't a spherical world, so it has no axis to make seasons...is there a canonical explanation for this?
Lastly, how did you do the coastlines? Just wondering.
