Figure drawing working from dark to light and with four colors.
The darker image was done with charcoal all over the paper and then starting to work out the light using chammy.
The latter was done with brown hard pastels, I chose white, black, dark brown and light brown as my four colors. (for the latter I had grey cardboard as paper)
Paper: Litoposter 72×104 (90g)
Paper: some grey cardboard A3
