I remember a quote by the famous pastel artist Harley Brown that in a painting, the center of interest needn't be big. On the contrary, a small center of interest when placed appropriately, becomes more powerful. This is well proved in this painting. The center of interest here is the bright illuminated part of the shoreline, which comparatively, is a small portion in the painting . This painting also serves as an example of dominant color scheme, which is blue here. The monotony of this blue space is broken by the introduction of complementary colors yellow-orange, thereby creating a contrast and drama in the painting.
Hope you enjoy it!
