Motoko underpainting

My initial "grisaille" or underpainting for the Ghost in the Shell pic. Usually in this kind of tecnique which originated from traditional painting, one should start with the blacks or umber plus you can use green for the flesh before you add the thin overpaint( consequent color paint washes , glazes.etc.)
