Creating colour variation
I brush in slight colour variations to break up the flat colour: more red in the nose, ears and cheeks; some yellow in the forehead; slightly saturated greens in the jacket; and reds in the scarf. The purpose is to be very subtle. I don’t want to change the overall colour – I just want slight variation, to give the character an appealing feel.
Blocking in the shadows
I set a new layer to Multiply and think about a light source – the sun is lighting my character from the front and top. I use a warm grey and paint in cast shadows and surfaces that are pointing away from the light source. It’s hard to get this right first time; I erase and try out different shadows until it feels right.
