John Brown Drawing Tips

Was watching a scultping tutorial by John Brown and he threw some great tips that apply equally well to drawing or sculpting.

He defines a curve as a series of intersecting lines. So if you want to exaggerate, it will still feel right if you maintain the ratio of the lines. (the red lines)

Then he uses the silhouette to check his shapes from his reference against his piece. He looks at where the apex (furthest out part of the line is) is in relation to the length of the line (here 3/4 of the curve appear above it), and at what kind of negative space the curve creates, and checks his piece against those things.

Pretty cool stuff. Easy to follow video, makes you feel like you can do it.
