Proko Drawing Basics Link

Nature does not contain flat lines. Nature contains volume. Proko teaches that you cannot draw a realistic human until you can draw a believable box in perspective.

A common failure point for self-taught artists is the inability to draw figures that turn in space. The Basics course tackles this head-on with a simplified introduction to perspective. Proko teaches how to draw the "bean"—a simplified torso shape—in various tilts and twists.

Without this, even perfectly rendered drawings will feel flat. proko drawing basics
