Mud Knife Painting?

I do this often. I have a bunch of paint left on my canvas and don’t want to waste it so I make

a portrait out of the mixed colours plus white and give myself a couple of hours, whether I’m done or not. If it doesn’t work out, it doesn’t work out. No time to think too much, which is helpful. This time I’m the model! Because of the colour it looks like clay which is kind of neat. All for learning creating memory muscles and the sheer fun of it.
