So I have Gimp and mind you I am not an artist, but I 'd like to start using Gimp to build out my worlds,from and city maping to worlds, I create, I need to know where to start. And I am unable to find the solid tutorial to figure out where to 'start' doing any of this stuff.

I can open layers and the like, but beyond that, its kind of complicated, perhaps someone could port me to the correct beginning tutorials?
