Thanks for the compliments, guys.
On my latest update, I've added in more legible latitude and longitude numbers (without removing the old ones from the border - that's just gonna have to wait, hahaha), done some more texture work (I think the major mountains are looking okay, but the basin and range region in the north central needs some work), and added in the peaks and sites icons along with trying out the road styling.
Still so far to go!
