Artwork of the Week

As I checked sketchbooks last week, I noticed that some of the first pages (especially regarding the principles art art) had been neglected. Take this week to provide descriptions and evidence of your understanding.
If you're unsure of a principle's meaning, do research rather than guesswork. Go in depth! For example, for balance, do you have an understanding of three major types: asymmetrical, symmetrical, and radial?
