I love maps. I don't care what they're for, how they're created or if you simply used a map generator to create something silly. (that would be me)
So please, share your best/favorite/whatever map here! Tell us a little about how you made it, and the map itself.
Mine is the aforementioned 'map generator'. I used this website to make the map and then wrote a novel based on it! It's pretty silly and not realistic in any sort of geological way, but it's been fun to write about places like 'The Bastion of the Gargoyle Duchess' (which is where my characters happen to be trapped right now!) and a lot easier for challenges like NaNo where I started with this map and then went from there.
I am another huge fan of Inkarnate. So much so that I actually subscribed/paid for it. It helps me out a lot with my giant epic fantasy series stuff. Here are the maps of some of the continents in my sprawling fantasy series I'm still working through...
I used to make maps in Photoshop with tutorials I found on the Cartographers Guild (unfortunately my like four year old bookmark is broken!) which was a lot of fun, if you have any interest / knowledge of Photoshop. (it doesn't require much!!)
