Thanks for the compliments, kacey. Unfortunately, the original relief map is a whole-world map of around 4600x2300 px and that is smaller in size and has a poorer definition than this one, so this is really as good as I can make it. Still, I think this last version suffered from reducing it to forum-friendly-sized. It does look a little better on my computer.
I have been drafting some of the other maps of the series - it could come down to eight maps, but a few would cover areas that aren't still fully "drawn" in the main-world-sized-map, so they may never see daylight.. Yet, I think I can get 3 or 4 down to "paper".

Thanks for the comments, reputation and encouragement, fellows!
