Hi all, I'm enjoying what you are doing here but I have a few points/suggestions;-
1] I see you are having discussions about the borders of the basins. Putting them in the same black as the shoreline makes it very difficult to remove them if you need to, surely the base-colour of the basin abutting the next basin base-colour gives a suitable "border".
2] I assume you are intending the finished product to be of use as well as artistic. May I suggest that the rivers are made the same colour within their "type/river size/basin size" as the current system seems to be quite confusing from the outside;-

This would allow anyone wishing to use the rivers to delete them by colour to the level they require.
Hope you don't think I'm butting in & looking forward to seeing the next sets of basins.
