Lovely!...
I had a strange thought when first viewing the tree on the left, as it reminded me of the anatomy of a human lung (upside down of course),
resembling the Trachea, Broncus, Bronchioles, and Alveoli.
Since trees serve to cleanse the air we breathe, if it were mine, I would title this "Natures Lungs"
I have been doing some mirror image tree studies lately and texturizing them, you could even turn this into a pano such as this if it strikes your fancy. It would be even more fitting of the title I gave it. Just a thought...
