Well this is about the best I can/care to do. It's mixed-resolution, some parts at the 2600 pixel size and some at the 1300 pixel size.A few cities are not super clean. Otherwise, at most zooms, shouldn't really be noticeable. The islands are just imported from the political map, unmodified, because they are so thin and plastered with names that it'd be too much of a hassle to remove the names and it'd yield a huge mess.
