Quite impressive, Jim. I love the graduated light values from bottom to top (or top to bottom); these value changes add a lot of pure interest to the shot.
The colors here are so....how do I want to say it?....CLEAN. It simply looks so pure and clean.
Compositionally first rate, truly. There is a really nice balance, sort of in thirds, with the highly illuminated lower image, the moderately illuminated tree (what a tree it is!), and the night sky with stars.
And of course, the "dimensional" effect rears its head again...all you have to do is study the tree trunk and limbs, and it seems to jump forward against the blue and black background. Almost graphical in a certain context.
I can also see some great possibilities in the limb structures for additional images; the globular leaf clusters also show some photogenic qualities.
This is one of those unusual shots that has a life of its own. You really cracked this one, Jim. Fantastic.
