I like the leaves connecting with the tips of their shadows. You are very correct about the artistic values of that effect. The greens and browns work so very well together, also.
For the invisible things of Him from the creation of the world are clearly seen, being understood by the things that are made, His eternal power and Godhead;... Rom 1:20
As Thoreau says "Simplicity is Elegance"...and you sure proved that very well here. It's such a beautiful photo..so simple, so peaceful. The shadows and the colours are perfect...a very very pleasant thing for the eyes!! VErena
