The image above is actually a crop out of the entire zone of Kalimdor, which I've rendered... but the 128 block height limit destroyed most of it.  I'm currently in the process of mapping all the textures in the zone, which total around 5000. 

Since the last update, the program now properly converts terrain textures to matching blocks.  I also fixed a few bugs with invisible walls appearing inside buildings.

That's amazing!  I especially like the way the hills look in the Barrens. 
One thing.  Would it be possible to change the Barrens into a desert biome to make the grass look a bit deader?

looks good, my only suggestion now is to make the barrens more "barren" :P

Minecraft doesn't have a "dry grass" block, but it does have biomes, which can make the grass look brown.  So the only way to accomplish this would be to edit the biomes, which can be done but I'm not doing it at the moment.

It's an idea I've considered, it will probably come last because editing biomes can't be done from the region file (you need to create a client mod).
