Wow. See? I keep telling you you can draw. This looks like it's popping out of the frame. Great shading. So much evidence of effort and improvement. Keep working on slowing down during the early contour process and imagine the shapes are flat (on a picture plane) and they'll paradoxically look foreshortened & 3D. Keep trusting the process.
On the observing/recording simultaneously- you CAN do it, you're just struggling to focus. Relax, try to block everyone else out, try to go slowly, focus is your biggest struggle besides apathy. Help me help you.
Everyone is encouraged to re-read pp.46-48 in 'Drawing on the Right Side of the Brain' and repeat this exercise as often as you want to to build both your perceptual skills and your mental L-to-R mode shifting skills. Everyone is also welcome to re-submit this assignment (decorating, filling with zentangle, expressing & interpreting the positive & negative spaces of the vase/face illusion) for a higher grade before the end of the semester.
