Prismacolour pencil crayons with Suzi Blu

This is my first attempt at a Suzi Blu face, shaded using Prismacolour. The exercise is from Mixed Media Alchemy, Workshop1 Gypsy Girl. The crayons are quite waxy and unlike anything I've worked with before in that they blend using colourless or the white crayon. The head is created on photocopier paper and then cut out and stuck to a canvas board background, before the hair and backdrop are created with paint and spray inks.

Shading finished.
