no, dont use charcoal for this, purple eyes, dont go well with sharcoal, its funny i jsut happen to have recently drawn a girl with purple eyes, and brown hair. this kind of things are best done with anime style, use shoujo style, you can use it as reference if you like. I'll give you the link to it, and if you ever want to know how to draw anything just let me know and i'll show you some good reference material, i draw for a living and have tons of reference. http://thefuries.webs.com/apps/photos/ just click on fanart and you'll find it. well as for the instruciton use eight and a half heads for adults and four for children, make sure the sholdiers are 2 to 3.5 heads for both adults and children, also make sure the lenth of the arms and legs match. purple eyes are drawn by making a purple cirlce, and then drawing a dark color from 2/3 of the eyes to the top to represent the center, and then a light iris with ligth iris.How should a teenage girl with violet eyes and brown curls be drawn?
Black charcoal. As for the technique, how about contour line drawing? Should be very interesting.
