Drawing in Perspective
https://www.skillshare.com/classes/Drawing-in-Perspective/1388176931
In this class, you’ll learn how to draw in perspective so you can depict any 3D object from a wide variety of angles.
In the class we’ll cover one, two, and three-point perspective so you’ll be able to incorporate objects at any angle into your illustrations.  I’ll be demonstrating these techniques on my iPad in Procreate, but you could use these principals for drawing on paper, canvas, or any digital drawing program.
