I made this drawing after reading Ch.4 - Inuitive Gesture. from Drawing from Observation. Brian Curtis explains that in order to safeguard the accuracy of our perceptions, we need to temporarily suspend the rationalizing influence of our analytical information processing until our intuitive and spatially sensitive intelligence has had an opportunity to react directly to the visual information in the scene. By moving our eyes quickly throughout the scene and transferring spontaneous light gestures to the paper, the left logical side of the brain is quietened, allowing the right creative side to blossom.
I can see that perspective is wrong on the left side of the drawing. I can also see some evidence of the freedom of gesture that comes from right brain drawing.
