Art is just a lesson in impermanence. I love that. I think for any artistic endeavor, the world disappears for the artist, or perhaps that is when the "best" art is made, when the artist leaves the now and goes into the eternal. That doesn't sound very mindful of me, but it's what I sometimes feel when I am singing or dancing, talk about lessons in impermanence. There ain't nothing left to show for that kind of art, not even a scrap of paper.
Your drawing is wonderful, you can stop saying you don't draw.
