I'm a sucker for Iceland maps. That said, I only rated this map 3/5 for multiple reasons, the two main ones being: 1. The bonuses are for too large for any style of gameplay, really---whether it be diplomacy or strategic. 2. The borders are a little sloppy.
Don't worry, I made both of those mistakes on my first map as well. Fix those two things (and add blue water, that's always nice) and your next map has the potential to be 4-5 stars.
TL;DR: Map's not as good as it could be, but it's a great start.
