allowing the painting to dictate

Same infatuation, taken to the studio. I have been playing with all kinds of different stains and underpantings.  I enjoy how much the stain or underpainting, in its spontaneity influences the painting. Remembering not to cover it and holding back the marks are key. Each mark must have reason. Constantly questioning...do I really need that color/mark?
