Well, this is definitely a work in progress. I darkened the Shadow Violet background by layering Moonglow over it. But...maybe that was not a great idea. I may need to touch in some dark greens in that purple background to make it look more like foliage...not sure.
For now, the following steps include adding some quin burnt scarlet and orange to the golden orange leaves, getting in some greens, and making sure I have the right values against the white areas to make it pop.
