This is definitely not step one but I was so discouraged the first day I worked on this that I nearly quit. My tree outlines didn't look like trees and I had no idea how to approach the grass. But, I did try again after a night away from it and liked what I was saw.
The ferns took quite a while since I drew them as separate elements in Photoshop and then sort of arranged them together and repeated them to make bushes. I think I had more than 200 layers when I was done, mostly of clover, ferns and flowers.
I decided the yellow flowers should be covering the meadow, but I still needed to add purple ones, as in Stephenie Meyer's description of the scene. I wasn't sure how to do that, and after trying a few different ones out, I gave up for a few days and thought about it.
It finally came to me that they could be just like the yellow ones. But it still wasn't quite there yet. I also looked a lots of photos of the Hoh Forest in Washington to get an idea of what the forest looked like. I decided I was missing that middle layer of foliage, that comes from little trees and large bushes.
After giving it some more thought, I came to the conclusion that I needed a lot more purple flowers. I tweaked a lot of little things, like adding shadows of leaves and ferns in the shadowed distance. Finally I got to the final product (see in the post below).
