Okay, so here's this world I'm working on. It's called Delmeiri, and its geography is loosely based on an east-west reversal of our own world's geography. I've been working on it for a while now, and I think I'm getting pretty close to done.

There's just one problem: the coastlines look more than a bit off to me. They look ugly and unnatural. What exactly am I doing wrong? And how do I fix it?
