Hi Ann, yes, I think I like that guy :-)
One of my instructors used to say "Not to design is to design by default". Therefore, everything in my work is a deliberate decision, even if it's a decision to embrace random chance or "wabi sabi". If you notice the sand dune, the size of the beads is graduated to help describe the curved shape. The paper strips forming the desert floor are graduated too but also becoming more greyed down in the distance for aerial perspective.
I don't remember who said it but,some major artist talked about having a large "vocabulary of marks". I try to have a interesting contrast and relationship from one area to another, even though my "marks" are not brushstrokes.
