Thanks, your majesty !

It annoys me that it annoys you .
I'm using shaded relief from Earth and Mars (for Mars, it's an oldie from USGS/Nasa & for Earth, it come from naturalearthdata.com). And I kinda paint them with a cloning tool at different level of opacity/
Concerning the landmasses, I've done a lot of tests and ended with this one... I tend to use some real shapes for inspiration (you can see a bit of Antarctica in the eastern islands of Golant, for example) and I've also used shapes coming from some online world generator.
