Here I tried various combinations of coloured pencils with a single marker, which means that I used the markers more or less as blenders. I used grays and light pink as marker blending colours over two or three coloured pencils of the same colour (for example: blue), and then with the marker blended them together.
I had no reference for the painting. In the beginning I just wanted to play with round forms. Then I had mussels in mind, then that image converted slowly into something more rocky-ish.
