After all these years, should have paid closer attention to lightness and darkness. Having recently practiced and giving values careful consideration, sketches have added depth and perspective. What was really surprising was how quickly a scene can be rendered with less labour by simply blocking out the major light and dark areas. These are 15 minute sketches…a considerable improvement in speed and likeness versus before relying solely on perspective and tedious detailing in hour long drawings. Exciting where this improvement will take the artwork.
