I painted this photo in January using watercolors
here, and wanted to see if I could accomplish any of the same things with oils and my palette knives. Not sure I could. In the photo there is more variation in the green behind the butterfly and flower. I did some underpainting, and let it peek through a bit. When I try to get a few different greens going, no matter how close they are, it starts to look like sponge painting--that is not the look I'm into. Instead I kept the background thin and layered the paint more thickly in the flower and butterfly.
