@Urfang I got the blue effect around the islands by layering different objects that were progressively darker shades of blue around the islands and made sure that they were on a lower layer than the outlines of the countries.
@Nerko252 I am already thinking of making a larger map where each territory would be broken up into smaller territories on the scale of my first map which was of Skyrim (http://warlight.net/SinglePlayer.aspx?PreviewMap=4948
). To get the borders of the bonuses to not overlap I went through and used the points on the lines separate from their bordering bonuses. I do not recommend this process for larger maps though as it was extremely time consuming, I just don't know any other way.
