I drew it. The map I based it on is explained in my original post.
In addition to suggesting new maps, I’d like to get rid of the huge inconsistencies of the Americas map looking like it’s drawn based off wild guesswork and the rest of the maps being of modern accuracy and geography. If they styled the maps off of ones from the late 1700s when the world was pretty much fully explored at a lower level of accuracy, they could have an aesthetically pleasing map that actually fits the time period of the game.
