This photo of beautiful oaks uses depth of field to draw your eye through the tree canopy all the way through the other side. All is in focus. It in neither under or over exposed. I imagine the shutter speed was average to high to capture the detail and texture of all elements in the photo.
Compositionally, the viewer is pulled into and through the understory. There is a both a radial and diagonal quality to the composition, and the rule of thirds is strong--defined vertically by the tree trunks and horizontally by the branches radiating across the canvas.
