Some sketches takes days to complete.
The initial pencil drawing took about three hours. The watercolor washes were done over a period of two days. I would love to see what a yellow background, rather than the white of the sketchbook paper, might do to energize the still life. Since the paper is so thin, I hesitate.
The color theme is double complementary, yellow orange / purple blue on the bottom and red/green on the top. The lavender in the lily facing away, as well as the yellow-greens of the lily bud and daffodils on the Roseville vase helps to tie the top to the bottom.
