This sketch shows how little information a drawing needs for you to make sense of it. If the artist puts just enough clear info down, you as the viewer can supply the rest. Often the results are more satisfying then if the image was fully explained.
It's figuring out the right amount of information that's the trick.
In this sketch I have only placed blocks of even shadow, but that's enough, you can see the elegant shapes of the gazebo wall popping forward.
Daily Sketching Challenge - would love to have more participate.
