The sketchbook I wish was around when I started out learning how to draw. This is Render Demo's 5th sketchbook and it covers the basics of drawing. Sketch along side the easy to follow instructions. The sketchbook is filled with guidelines and templates for you to practice on. I'm pretty sure almost all of you here already know this stuff, but still worth brushing up on the fundamentals!
