This image is an oil but I often challenge myself to  watercolor from copying one of my oils. This way I use layered colors and more color and the result is a classically painted watercolor. I start with the warm yellow-oranges(not tangerine red!) then add reds under the dark colors and then go directly to my darks. Three steps and I use a light brushstroke to layer paint. The highlights on the egret will have been left from the original yellow-orange wash.
