For this modified drawing, I used a sketch of a Bird of Paradise flower that I made with colored pencils onto a monoprinted background. The flower's colors are vibrant and the background is an interesting contrast as the colors are pale and subtle.
After I scanned the image into my computer, I bleached out the background but kept some of the color. There's even more contrast now.
On this one, I added another subtle background and added a black oval to ground the image.
Here's one where I played around with the texture of the flower, letting the background peek through.
