When I see details like this I discover that I’m more of an abstract artist than I realize. But I love the visual incident of passages like this one, this detail of the painting Distant Oak.
I rarely — almost never — paint with acrylics now. I’m an oil painter. But I recall I did love the ways you could put layers over top each other quickly — and could with the addition of some white paint — recreate the bottom layer again and thus play rather easily with transparencies and texture.
This bit of abstraction appears on the lower left hand side of the painting.
