This week's palette "Femlin" was just a sequence of brush strokes made with a Japanese calligraphy brush. It's an old brush—one I've owned since college (!)—and it keeps losing it's point.
I was painting random mountain shapes at the time, with cracks and furrows in earth. The brush would split into random forked shapes and served well to create unexpected linear shapes in some areas where I needed that. But off and on I would need the brush to form a good point for drawing lines in the rocks, so I kept shaping the point by swiping the hairs of the brush on a piece of scrap paper.
Naturally it made a shape that caught my eye and insisted on being taken further. I took a pencil and added the profile to the right side. Later, when I was using white paint, I spotted in stars and other details.
