I inked in the lines for today’s experiment, after painting a graded wash (blue-to-red-to-yellow). I inscribed the curved shapes as precisely as I could within the inked boundaries. The central ovoid is shaded for a three dimensional look (resulting in a spheroid); the blue circle is a flat planar disk; the yellow shape seems to have an incomplete border. These figures, taken together, neutralize any signs of depth that would ordinarily accompany converging lines.
I like the final configuration of this painting, which was not my original vision. It works as is, however.
