Watercolour vs acrylic — what I reach for

Acrylic is for certainty: opaque, fast, forgiving of layers. I use it when I know the image and need it to hold.

Watercolour is for surrender. It moves on its own and rewards a light hand. I reach for it when I want the medium to be a collaborator, not a tool.

Most of my celestial work lives in the tension between the two.
