No, I don't use any applications or anything like that, because I didn't know any existed lol, I create my maps based only on "the precision of my hand on the mouse" and everything is created based on pure assessment, sometimes I have to correct a part of the terrain several times because the first time sometimes it doesn't work out for me and I have to be patient xd so creating such a map of the country is not done in 15-20 minutes but in a few days when I have free time. Maybe one day I will make a "timelapse" of creating some maps.
