The tree and the foreground weed are both quite lovely, but they are competing for attention, which makes the picture feel out of whack. The light strengthens the effect, but it's not entirely the light, it's simply the juxtaposition of the two objects.
The road leads to the tree, which stands solitary in the distance. Strong, eye-catching. The weed is a blotch of color and texture right in the foreground, also eye catching. Printed large, to visually separate the two, would probably help. This might be quite successful printed 11x14 or larger, but in the small size it's a little visually confusing.
The colors are quite wonderful and there is much to love about this.
