What a splendid map !!!
It's so bright and contrasting with the ocean that it literally jumps out at you!
As for the rivers, I really have the impression that this is a test map for joining the river police!
It must have been madness to make this hydrographic system coherent!
The style is a bit different from what you usually do, it seems to me, but if the map dates back to 2017, that must be where it comes from.
Superb work, in any case... as usual!
