Awesome to see the finished map after all the teasers on Instagram! It's truly beautiful and has a nice authentic feel to it, prachtig werk!

As for the lettering, what software are you using for the text? I always use Photoshop and what I like to do is add a white inner glow from the center of the text, with some noise added to it. This gives the impression of the text being actual ink. I've added a screen capture of my setting for that. It's not the same as actual inked text, but you might give it a try and see how it looks.
