This first image shows the first wash of pastels with Mineral spirits to capture shadows. My substrate is a primed mat board. I used Art Spectrum Colourfix fine tooth multimedia clear primer.
2nd wash filling in basic colors.
Here's the final painting. The underpainting wash technique was done on location. I ran out of time ( had to be somewhere else) to finish the work outdoors. I snapped a photo and used it to finish the work in my studio.
