Thanks to  soulshelter for the suggestion!
Though, to be honest, I was hoping for this one. I want to do a less sketchy tundra picture sometime, since this is the area Sonata is from.

(Yes, their world has a green sky. :U )

Feel free to suggest other biome sketch ideas.
Not rainforest, though. That environment doesn't exist here, except in one certain location. I'll do a nice picture of that, sometime. It's a special place. 8)
