The advantages of using acrylic under an oil painting is that you can actually save time by working out the compositional issues, the colors, values and create richer texture with water miscible oils over acrylic. In exchange for the advantages, water miscible oils require more initial prep time in mixing water miscible linseed oil to the paint to create a buttery creamy mixture. Jerry continues working on the pool of water from the bottom up to develop the richness of color, all the while allowing the acrylic underpainting to show through. He finishes up this episode by adding reflections of rocks, trees and grass in the pool with short broken strokes.
