Not a lot of time over the past couple of days to work on this, but I’ve managed to tweak some of the landforms a little. The planet resembles a mirrored Earth a bit less now. I’ve also started painting altitude contours on the map. So far, just the very highest peaks, the Andes- or Himalayas-equivalents, but the next few layers should cover all of the land areas with colored zones to indicate altitude.
