Here is the final in the series using a process of doodling in the dark (ok, candlelight).
In this one, I learned how habitual it is in me to pull out a humanoid form or a face no matter how abstract the initial doodle. That’s why I am also playing with which way is up on these. I did a fair amount of the coloring on this with it turned 90 degrees clockwise, but decided I like the composition oriented this way. As always, clicking on the image shows a larger version.
