Shadows, shapes and lines are essential prerequisites to realistic art, especially in plein air paintings. These elements are constant in nature, no matter where one turns to. Shapes have been in turn used by all artists as an essential element to define composition. This work of bushes, next to the water, is no exception. Rhyn’s rhythmical rendition of these masses and lines is very obvious. He gives meticulous attention to detail, particularly to the bigger shapes, as in this instance, to the leaves making the painting buzz, with energy and rhythm.
