Planet Na2CO3
I came up with a technique by using soda grains to create new surfaces and textures on ink. The soda seizes an amount of the ink what wil create beautiful veins and texture. I like to use this technique for example to illustrate landscapes of planets, as you can see here. I also made an illustration with this technique for the poster of a VR opera called "The opera of the falling man". In this illustration you can see a man on top of a rock floating through space.
