Lesson 1: Lines, Ellipses and Boxes
So assuming you've been reading diligently (starting from lesson 0) and have followed the instructions of completing only the recommended number of pages, then you're probably wondering, "what do I do now?"
Well, the smart thing would be to get your homework reviewed. Let's say you've done that already, and want to know what your next step is going to be.
Your next step is to tackle the 250 box challenge. This exercise will take what you were introduced to in the rotated boxes and organic perspective boxes exercises and work on developing your overall grasp of, and comfort with, freely rotating forms in 3D space. The notes and video there cover techniques that will help you do this as efficiently and effectively as possible as well.
It's a tall order, but most who've gone through it have shown considerable improvement - especially those who've read through the notes and applied the error-checking approaches consistently.
And before you go, I hope you've been able to get your work reviewed by other members of the community to make sure you're still on track. You can watch me get my work reviewed by Uncomfortable, live!

Cottonwood Arts Sketchbooks
These are my favourite sketchbooks, hands down. Move aside Moleskine, you overpriced gimmick. These sketchbooks are made by entertainment industry professionals down in Los Angeles, with concept artists in mind. They have a wide variety of sketchbooks, such as toned sketchbooks that let you work both towards light and towards dark values, as well as books where every second sheet is a semitransparent vellum.
