The dark deep shaded area just above the ground is almost black and detracts from the beautiful upward flow of the image. Particularly because it goes from light area to a dark area of almsot no interest or detail. At the same time, I think if the trees were not so dark in the front, the image would be better. Sort of like adding fill light to the scene. But maybe bracketing would achieve a better result. These extremes are almost unavoidable in a scene like this. But keep at it because the composition is good and the feeling of exhuberance between the sun and the trees is definetely there.
