Work on "Painting like Andy" project. Focus on blending in the scales of the snake, leaving spaces of white for highlight. Be sure to create shadows around the sides of each scale to create an overlapping effect. Come up with creative ways to use only primary colors to create the same scale effect as the original. Blue is to black, red is to grey and yellow is to white. This compeletes the full value scale, the same way that dark green is to black, light green is to grey and pastel yellow is to white.
