It's been awhile since I've been able to work on this. It was supposed to be something to fill in time between other projects but the others have taken all my time. I'll try and keep working on this just to get it out of the way.
I added more splotches of greens trying to get closer to the darker values. Next I'll be lifting out stems to try and get a feel of where the plants are standing so I can make the structures more realistic.
