Yes, that is exactly how it’s meant to look. To change a fill style, hide everything but the sheet that has the fill you want to change. On the left hand menu, right click the Change Property tool, select Change Fill style, select the fill style you want change, press D then select the fill style you want to change it too. To rescale make sure the fill style is the current one, you can set this by using the eye dropper tool on an appropriate polygon, right click in the Fill Style box on on the top right, you’ll see scaling down the bottom.

Ok. So as far as selling maps goes; you can sell maps you make in CC3+ no problem, you can't re-distribute Profantasy's artwork, for example make a page of symbols or fill styles and sell those, that is a violation of the EULA, but a proper map is fine.

If you're going to 're-interpret' a map (copy it in a different style) from whatever source and sell them without permission from the copyright holder you open yourself to legal action. If you do a completely new version that is not based on the original, you might be OK but seek legal advice just to be safe. I personally wouldn't because it is simply not worth the hassle.

Dsitributing them for free as 'fan art' and with proper attribution, will not likely land you in hot water but that depends entirely on the copyright holder.

One thing you can do, is send the publisher/copyright holder a letter or email and ask for permission to sell them directly or offer them for 'free' via Patreon or similar. The worst they can say is no...

As others have said if you intend to make money from Cartography, either work on commission or create original pieces. It's the only way to 100% avoid legal issues.

Lovely work Mike, really superb and an act of true dedication to the craft.

I know it's rather late, but I would've added a colour key on the vegetation layer to mask out the water courses.

Firstly, delete your current grid, then turn on the Grid and Snap Tools (bottom right), make sure your grid size is set to be the same as the grid you want shown. Ideally, there will be grid dots on the bottom left corner and top right corner of your map border, if there are not you're border size is incorrect for the grid you want and you won't be able to place a square grid. Then re do the Draw:Hex Square Overlay command and before finishing click on the Select Points button. Click on the bottom left corner of your border then the top right corner. Your grid should now fill just the map border perfectly.

@Fersus In response to your question re commissions.

It started a couple of years ago. There was a monthly challenge over at the Cartographers Guild to build a random dungeon, after some fairly ordinary efforts, I re-did it, wrote up some adventure text to go with and submitted it as a One Page Dungeon entry, The Crypt of the Witch King or Who's Your Mummy. There is a CC3+ version in the Old School dungeon style in my gallery. Anyhow, fast forward a bit, and I pitched an idea to the publisher of Mythras, my preferred FRPG, to produce one-shot adventures like the Savage Worlds One Sheets, I also mentioned that I do cartography and submitted my OPD entry as a sample. That led to some commissions for their Classic Fantasy line, primarily B&W old-school style dungeon maps. I've done a couple of other projects for them as well and I've been doing all their CF stuff since (you can see the latest in my Commissions album, the Ancient Tombs style). This is by far the largest city I've undertaken - and if I get others, which I think is likely given conversations I've had with the CF line manager, I will be charging a lot more, I can tell you! So that's it. All of my commissions, apart from a private one that I've yet to complete (sorry Allan!), have been for them. They are great to work for and very professionally run.
