Okay, first off I think you did a really good job of finding all these spots to photograph and the right time as well. And you capture them with every evidence of composition skill. The title makes sense, a ray of light is directed specificly on the tree, but I think allusions to the source of light should be hidden: the top part of the photo. That way the light behave more like a spotlight. Also the other trees in the photo really distracts the solid texture of the rocks.
