Hi Will-

A couple items for consideration.

Is this map representing an entire planet? If so, you may have some issues with the overall shape of the continents reflecting the distortion you would see near poles.

I'm personally not a big fan of the coastal glow effect - might be that the cyan is a bit to intense? But that is personal preference.

You've used the same bump-map like texture everywhere not mountains, and it stands out as a bit too regular (especially if it is at a global scale) You might want to mix it up a bit more.

The frame has a very regular repeat at the top and bottom. You might want to find a larger pattern to use if you want wood-grain.

I thing you did a great job with the political borders - logically placed by following major terrain features.

Keep working on it!
