Fantastic work; I think it may be up in the top 2 or 3 ones of yours I like the most. I only have one tiny critique: the rivers are hard to pick out (at least for me). Maybe make them a bit darker/bolder? Not the ones that flow through the forests - those look great - but the ones in plains regions. Or maybe it's just my ancient eyes that can't see them.

Anyway, this is a stupendous piece of art, man.
