Colour dodging

Using my mask, I knock the character out from the background. I want the shapes to stand out from one another, enabling the character to be read quickly. I create a layer and set its blending mode to Color Dodge. Next, I paint in dark neutral tones with a soft brush (IFX 01 Airbrush). Then I erase parts with a sharp, Chalk brush (IFX 01 Chalk Chisel).
