Hmmm … its pretty good. Although probably not as good as your last (red/blue). A bit too dark and the colours are a bit off. That bright green is really out of place. Also brighten it up a bit more, add a few more lights.
Where is the l-system used?
Looks nice 
As for the l-system, I’m guessing it’s the purplish plant in the right inset.
I really like this one.
Great render and the lighting at the tree gives it a very good ambiance.
