I decided to start with the pink rose, as it is the most dramatic. Here is my first step. Sometimes when I do something that's basically all one color, I paint the first color, then add, getting darker with each step. But as with this one, sometimes I will paint each flower petal separately, so that my shading is exactly the color combination I want. This is larger than I originally planned. The paper is about 15" square. It's a good start, I think.
