|Been Down This Road Before, pastel, 9x12|
I used a mostly monochromatic underpainting to set the value structure, using a dark blue Nupastel to block in most of it and a very dark reddish-purple soft pastel to intensify only the darkest areas. Straying a bit from the monochromatic structure, I also added just a touch of a yellow-orange with a Nupastel to the lightest areas (the sky and road). Even for my monochromatic starts, lately I've been including a warm color to underlay my light areas when the ultimate color used in that area will be on the cool side...I find that this keeps the color from have a whitish, chalky look.
Sorry I don't have photos of the initial block in on this one.
