So this isn't even close to completion (and I have only two months left until I graduate and very few mods left to work *laughs nervously*) but I thought I'd post a progress shot. It's going to be six biomes since it's in the AP bio room. The first is taiga biome:

And the second a desert:

I think I want to do something with a lot of reds in it next, since both are pretty cool and subdued.

I haven't painted a landscape in about two years and I'm starting to remember why I stopped :P But its all starting to come back to me again.
