A New Painting: "Large and Small Circles"

I've finished the last (on the right) of a group of four vertical paintings. Each painting has slightly different dimensions, but their overall similarity of mood makes me think of them together.

Large and Small Circles, egg tempera on calfskin parchment, 9 1/2 x 7 in.

This painting is the only one with a second color having some dominance. The painting on the left in the group photo, Angled Bar, also has a blue color at the upper right, but it is closer in hue to the main color. In this new painting, I was drawn to the large split circle; we can see that its bottom portion is bent upward, catching more light. This adds a bit of the unexpected to the image.

Then there's that little rectangular hole, asking for attention.

The large circle is made up of flat planes, but the smaller ones below are rounded. The two of them side by side, with their volume, gives them enough visual presence to keep my eye moving back and forth across the surface of the painting.
