Credit Card Sunflowers Watercolor

Start with these reference images:
Starting at the top of the page, use a variety of hues, keeping the values very light. Continue on down the page until you start to indicate a vase. The light source is coming from the right side, so the left side of the vase will be a darker value. Drop in a background color. I have used contemporary colors.
While your pigment is still wet, use a credit card and scrape out shapes like petals, where the light would be hitting the flowers (refer to your value study). If you are not getting back to the white of the paper, you may not have used enough pigments, or your paint was too dry when you went back in.
Let dry. Now go in with mid-tone hues, starting to show some of the petals and foliage of the plant. Indicate a center of the flower - show a change in value. Soften the edges of the center.
The final wash will consist of dark values. Once again refer to your value study for those dark shapes. Connect the shapes in an interesting pattern. A table edge may be added and shadow from the vase on the table also.
