I completed this experimental mixed media painting a month ago. The circles were completed first.
I masked the perimeter before adding the ink background. Finally, salt created blue shading in the black.
Unfortunately, some of the watercolour came off when the tape was removed.

What a great outcome, love your experiment very much. So many possible interpretations too.
Thank you, I like it too.
it reminds me of a cover from a sci-fi paperback from the 60s – and this is a compliment.
Thank you.
