This doodle/painting reminds me of cells moving along through a vessel. I have been playing with even more of my new art supplies recommended by some of the artists I took online classes from recently. Betty Franks recommended Nova acrylic paints because the pigment is so rich. I heartily agree!! There is so much pigment in the Nova liquid paint, that comes in little jars, I can hardly believe it. Great paint!

Here is an earlier version of this painting.
