I begin by transferring my drawing to a full sheet of 300# Arches paper. I thoroughly wet the paper on both sides, let it swell and then staple it to my backboard.
While the paper was wet I dropped in oranges, golds, and pinks into the rose blooms.
I added a warm neutral background on the right side.
I added the background on the left and the woodgrain of the table
I painted the leaves and stems
Finally, to increase the contrast with the roses, I darkened the backgrounds, and laid in the darkest darks.
