Measuring helps an artist copy anything accurately. If you’ve ever tried to draw, and discovered your subject’s nose is too short or ears are too large AFTER you’ve started shading, you’ll find this technique will save you time and effort. Using the eyes to measure against the rest of your subject’s features, lightly outline where you would contour the entire face. Start with a light pencil, like and H4 to H2, drawing without enough pressure to dent the page and you’re set to go!
