After letting the base dry for a few days it was ready for paint. I sealed the cork and created a uniform surface, ready for paint, with a layer of Mr. Color gray thinned with Mr. Thinner for a tough base and let it dry overnight.
Then it was time to start applying color. I decided to try to apply color modulation to help build a sense of foreground / background and to work with the manhole cover and wall to help achieve depth. I started by applying a gradient with the near left corner being almost pure white and fading through gray to almost black at the back right. I felt that this diagonal gradient would help add some interest to the overall composition.
Than I picked out different details and areas of differing tonal values where I wanted to call attention to surface and material changes (the curb and crown pavers).
Then various washes were used to accentuate the gaps between the pavers. After that I used white oil paints to pick out highlights. I kept the washes at the left front corner warm and transitioned to cooler washes toward the far corner.
Next installment – details.
