further development of the previous circles versus arcs. creating much more depth to the shapes as well depth into the entire sketch. The way the individual globes interact across each other is also cool.
Taking the shading idea explored in 'In Class V2' and applying it to overlapping circles and arcs. the alpha has also been randomized to give a more natural effect and improve hierarchy.
The simple pattern I did in class. I like the way the two identical patterns are slightly offset which create a almost three dimensional stairs effect.
