Okay, now I can see that your terrain icons are stepping all over each other and cutting each other off or overlapping in ways that don't make visual sense. I suspect that's a matter of practice and experience with the program. Since I don't have CC (which I had the money), I can't really help with that. If you can move individual symbols "up" and "down" in the layering, you can fix it. I hope one of the CC experts will give you some pointers.

As for scale, if those are miles and this is a world map, I would have to assume this is a flat world, so some of the guidelines for a globe would not apply. (Rivers should still flow downward, unless some specific magic would counter them, but climate zones caused by a spinning world with varied angles of ground to sunlight would not emerge.)
