Okay, sorry for the late reply I didn't get any notfications.

I am using Photoshop CC 2019 and will probably try to draw on a 3D sphere here to make stuff look a little bit more realistic and un-distorted (?).

The purpose of this map is to get an idea of the whole world I am setting up for my novel, which I want to write in a few years (after the worldbuilding is done). So it's more like an orientation for me as well as a referring point for measurementt (distance etc). Most of the novel will play on only one continent so a world map isn't really needed but I imagine a larger world and want to make it at least kind of realistic from the beginning.
