While not an entirely original concept, your photo certainly has a unique position. The perspective, to be more exact, capturing the view from a much lower stance shows the ground cover which is usually a less noticed dimension of any landscape. The vignetting on the upper half of the image creates a question of time of day, but is countered by the shine from the sun hitting that natural 'v' in the trunk of the tree. The shaded hills create extra depth and the seemingly abnormal (though what is abnormal in nature, really?) clouds make this dreamy. The only downfall I could point out is that this shot may have been more successful in a landscape frame versus square/portrait frame. I would recommend shaving off more of the sky than the ground and just pull it out horizontally.
