OK. So I studied your code which - as always - is brilliant for its 
simple and smart solution. I wonder how you came to think of this?

One question: leaf_tl was generated by you, I suppose. I can see a 
number of ways to do this, in particular by combining leaf_b and leaf_c 
(The inversed twig of leaf_a is added of course) in a smart way in GIMP 
for instance, or by simply tonemapping in GIMP.

In any case, there is some work to do next time I need a tree! :-)

Thanks for sharing! Keep corona-free!
