Hey loving your work. Im a 2 dimensional artist..canvas and paint but as i also choose the life of a nomad with no home its become really impractical to carry everything around from country to country so seeing your work has reminded me of the possibility of creating digital art (oh goodie another learning curve lol)
It could be a very good solution for a nomadic lifestyle. Digital art comes indeed with a learning curve. If you want to do something with a phone or a tablet i can recommend corel paint. It is not free but I am very happy with it. All you see on my blog is made with it. Another thing to take in consideration is having electronics that measures the pressure you give. I have not a lot of knowledge about that but i have felt the difference.
Ps I am grateful you like my work
