Hey,

I'm working on my world map, but I want advice on how to make these coastlines look more realistic. I know good techniques to make these coastlines rougher; I even know how to apply said techniques differently to different parts of the map. I have the tools; I just don't really know how to apply them.

My overall goal is to get my coastlines looking like they could be those of a real Earth-like planet, with similar size, climate, temperature, sea level, etc. I'd like some guidelines to help me get closer to that goal. Any ideas?
