Hello, i'm new to mapping and am rather, artistically challenged when it comes to most things. I find one of my main issues is the fact that i like straight lines, boxes, things that can be measured easily and precisely. When it comes to mapping however how lands form and whatnot there are no straight lines, or at least minimal amount of straight lines. As a result i am here to ask how do i get away from trying to use straight lines for everything? How do i make those wandering rivers and rough coastlines that make the maps here look true to real world physics and geography. Thank you in advance to anybody who can answer my question.
