I actually liked how you had the title originally; now it's hard to read 'the empire of'. To me anyway. That could be because I'm old and blind though.
Also, by taking away those nifty bevels/cliffs around some of your coasts, I feel like you're going in the exact opposite direction of your thread title. Ultimately though, you have to go with what YOU like, and really, you're a fantastic artist, so I think whatever you come up with will look great.
