I'm bumping this as opposed to making a new thread. I've tripled/quadrupled the mapped areas to now include Mount Sovereign (the huge Western mountain) and the Darkstone Isles to the East. Here's a much better viewer:

If you don't have or want Silverlight, it may default to AJAX on the normal link:

And the original full size map (15,000 by 8,000, so it may have issues loading in the browser):

I'm still on the fence regarding placing cities/agriculture/etc. This is effectively a game map that players will be able to populate with their own cities, etc., which puts me in a strange position -- if I draw in towns and cities and players create new ones, does it look too awkward when the players just get an icon while the NPC city is mapped? Regardless, I'll be able to place some icons for general viewing soon.

I will get into coloring and variety, but I feel the terrain mapping and water takes precedence over it at the moment.
