wow u really are good! i have a friend who tries to draw realistic pencil portraits. is it all about practice? (well obviously, but i mean u dont grid or something right?) or do u use a light box? i only ask because u obviously have everything placed so well! )
I do not use grids, go to the eye, I do many layers of graphite powder and the light areas get with the rubber gasket, for details use the pencils, it just takes a lot of practice and patience
