@Quenten :

No, I cannot use these for the atlas. A re-imagination of a classic map (With name changes, a lot of those place and god names are trademarked [then again, many are not, because they took them from existing religions and beliefs]) may be ok, but not a straight-up conversion like this.

Also, you cannot post the original FR atlas maps here, they are part of a comercial product, and even if it is not in sale anymore, those copyrights still belong to Wizards of the Coast/Hasboro. I think remakes are fine though under fair use cluases, unless Ralf says otherwise. I didn't remove any of the .fcw's, because you seem to have posted the converted version twice anyway. Low resolution images of the original maps for use as comparison with updated versions are probably fine as well, but please don't do high-res exports and put them in the gallery.

Change the fill style resolution settings. Try to divide the numbers by 4. That should fix the pixelation.

Some of that text is pretty hard to read. That red and brownish text need a much more powerful light glow to be readable.

It is possible, but I don't recommend it. Making a city map on an overland map adds a lot of small details in one spot. This tends to just look like a mess when you are zoomed out to enjoy the overland map itself.

Additionally, city maps tends to get a bit heavy, so adding multiple of them to the same map isn't a very good idea performance wise either.

And you will need to do some manual tweaking regarding sheet setup, since overland maps doesn't have the same default sheet setup as city maps.

Instead, I recommend you use a regular city symbol and map the city as a separate map. Add a hyperlink to the city symbol instead, so you can click it to go to the city map.

A lighter and better way of making a city on an overland map is to actually combine multiple overland city symbols. This doesn't give you the same fine control over houses and streets, but it still look like a city, similar to these maps here:
