At the mid stages of the drawing most of the work is increasing the values. This is a gradual process of layering a number of different pencil grades one upon another starting with the hardest and working toward the softest grades. There isn’t too much graphite layed down in the foreground or shadow areas yet as there is a danger of accidently smudging into the area of the wedding dress. When the drawing is finished it should look as if the couple have their top halves in light with the bottom part of them in shadow.
