Beautiful work! The terrain seems very realistic, and I love how the mountain relief looks. Wilbur's rivers always come out so pretty. If I had to nitpick something, I'd say the dark outline on the coastlines is a bit too strong for my taste - especially the massive shallows to the south become bit of a mess in my eyes because of it. But other than that I really dig the look of this. The time and effort shows. Kudos!
