So, this is a continuation of the world mapping project I began a few months ago using the 13th Age Revisited style. I took onboard a lot of the suggestions people made for those maps, and one of the regional maps which came out of it was this:

The party's campaign is focusing on Cimmetra, and rather than stick with the broad-brush continental region map, I decided to something more nation-scale, falling back on the Ancient Realms style (which is one of my favourite looks for an overland map). I also wanted to delineate (vaguely) the regions within Cimmetra in terms of heraldry (the players are getting a companion document which outlines the noble houses in question), so I fell back on Cartographer's Annual Vol. 2's Heraldic Symbols style.

Obviously the setting required some alternative/bespoke textures and a little bit of photoshopping to make them work, but I'm fairly happy with the outcome. All in all, it took about a day:

As always, all feedback gratefully received!

Thanks for this! After a little meddling, following your advice, I've managed to get this working. I've also added a more subtle randomisation to the pitch, which has the added benefit of giving 'similar-but-not-the-same' colorisation when constructing a block of a given colour - which is something that always appeals to me. I've made a tool for each texture using the same macro, which helps further with the variety.

Here's an example of the eventual output:

That's amazing!

Thanks! Here's hoping the players like it. I just finished a mini-gazetteer for them (it's a new campaign) that ran to a few thousand words.

And, because the heroes need places to go to as well as somewhere to come from, I tried my hand at a Spectrum Overland map of the surrounding area at local scale (25mi across):
