It works though... with the 3 lines, it looks like 3 rivers... so either 3 or river would work


The only issue I had, honestly, is that the river is so much lighter that it's difficult to assimilate.

I don't think it matters if you change the name, but saying "shown sideways" in the key might throw off the feel of the thing a bit, so maybe kawasan is a good compromise.... just make sure that doesn't already mean something else

Either way, it's still a beautiful concept, and a beautiful map
