8.5"x11" brown Conte crayon in sketchbook, done on location. This old storage building was across the street from the, I think it was a shoe factory, on Aggie Road in Jonesboro AR, 1980.
While I was working a young Asian fellow walking by stopped to watch, complimented my progress, and very carefully pointed with his thumb to the front just under the eave and said, "Needs more shadow here." Then he wished me luck and walked on. I, since he was right, put more shadow there.
