This is a brilliant piece of work already, and I can't wait to see where you take it.
It looks like a satellite photo made through a fantasy lens if that makes any sense. Or maybe something you would see in a scrying crystal ball.
The only thoughts I can offer:
Both the two little towers and the waterfalls caught my eye as being off perspective when compared to the top-downish mountains and rivers. The forests kind of get away with it, but also clash somewhat near mountaintops.
Just food for thought.
Anyway, keep up the astounding work, Pasis.
