The black marker line is still visible, but colour is added to give the drawing a little more life. In this style, the colour is done with shading and highlights for a more "finished" look. Head and shoulders or with a "theme" (small body) attached, depending on your preference (theme costs extra). Can be done in marker and coloured pencil on paper or digitally. Your choice.
