Sorry for the unfinished sketchbook doodle. I’m trying to apply your suggestion to see values as shapes from your critique two weeks ago. I even closed one eye and squinted the other while I was shading some of the darker values. I think I need to continue the dark value through to the lower left of the composition. The scan cut off the left and bottom, but the top and right are pretty much the way I drew it.
