Just a practice sketch in Photoshop with the impasto brushes and one of my surfaces, starting with an underpainting. I’m using one of my Art Surfaces for the underpainting and then the rest of the paint doodling is just on a plain layer on top. I’m mostly painting with the Stump Trough impasto brush which is free in the Sampler set!
