Multiple sketches. They don't read well after scanning since they are prepared by graphite. The numbers in the bottom two are my process to reduce the values to five so as to get a simplified graphic read. The top two are more subtle in shading, but less able to communicate digitally.
The background challenge is to go black for a graphic look which would be my tendency since I lean to the contemporary, or the atmospheric background which puts the knot in a space to relate to. The atmospheric background will read more dimensional.
