These are Ranunculus.  As you can see from these two photos, I continue to paint shapes that redefine areas and create the illusion of space.  The flowers have color on them, but still have the appearance of being soft and white.  I am not quite finished with this painting, but I need to stop and study it before adding the last touches.  I may scrub out some of the dark shapes and I am still not sure about the background.  I originally wanted to cut the paper to make it smaller, but then added the lattice work for contrast.
