Here I have added deeper colors to the shadow areas and have come closer to finishing the stem and whatever those things are that open when the buds open. I guess I should research more about plant anatomy!
Next, I will step away and ponder whether to deepen the sky color and add more darks. the peony petals are so translucent I don't want to lose that look, so I may be close to finished with this.
I'll post the final version when I figure out if I am finished.
