Artychoke

This is a new exercise for my colored pencil class. We used several methods to mix color when drawing this artichoke including complementary shading, local color, and also grisaille. This piece is done by laying down a tonal drawing in prismacolor black grape, and then applying the full color over that layer.
A friend told me to stop my drawing at this phase. She thought it would be more interesting than completing the artichoke.
