The 66th sketch looks like a dark and light 66. Metamorphasis is what it is. The sketching process took a lot of work. Too much dark, too much light, too much dark in the light, too much light in the dark… Too many lines, not enough etc. It was a process of finding balance. I had no idea what I was sketching. I saw it take many shapes before this.
What this is, is a combination of potentials that finally collapsed into this.
