Recycle drawing project

I was recycling old color crayons and some white sheets. So the main idea was to develop a work of recycling. Well, this piece is an exercise about what I remember from memory: the canon of the head, lights, shadows. I take only two planes, the main subject and the background. The basic colors of skin, hair and background in cold colors. Regarding the pencil
art, just gently bring the stroke of the pencil in one direction. To finish the drawing scan it and I added an artistic filter called fresh fine texture. Well, I found it funny recycle materials, to recount what I learned and mix with digital technology.
