For some reason I like painting window boxes. My neighbor always has the most beautiful window boxes with great colors and she arranges them so nicely. Every year they are a surprise because she changes the color schemes.
Here is the photo and the painting. My emphasis was on keeping the brushwork loose and using warm and cool colors in the flowers and leaves. I used a pink underpainting to help keep the flower colors bright. Then blocked in the big shapes before putting on the last layer of brushwork.
