@Azelor I'm just using Photoshop's clone stamp tool to paint from a cut up, rotated, flipped etc satellite map of Earth, so it's actual terrain just going where I put it.

@Veldehar The tropic lines and ITCZ would be a good thing to figure out, thanks! As for the deserts, I've been talking to a geography teacher at the university I go to and their location is accurate, although we did talk about reversing the rotation of Earth, so maybe that's why she suggested the deserts on that side of 'horseshoe' mountains. I'll double check about that before going farther.
