Drawing is a form of visual art in which a person uses various drawing instruments to mark paper or another two-dimensional medium. Instruments include graphite pencils, pen and ink, inked brushes, wax colour pencils, crayons, charcoal, chalk, pastels, various kinds of erasers, markers, styluses, various metals (such as silver-point), and electronic drawing. An artist who practices or works in technical drawing may be called a drafter or draftsman or draughtsman.
There are various techniques in traditional pencil drawing such as, Hatching & Cross-Hatching, Smooth Shading, Outline Variety, and Circular Technique. The best way to get better at drawing Realistic Portraits is to keep practising and learning using Study Courses and other tools to get better.
