Getting Closer to a Mapping Yih

I'm figuring out UV unwrapping in Blender. I think my next step is to draw a model with techtonic plates, then I can sketch landmasses over that.

The only set feature is that the yinrih's cradle continent, which I am calling Damsback (dam's back) in English, is taller than it is long, straddles the equator, and has a rain forest biome in the middle with a grassy steppe to the south.
