So what speaks to me in this one is the texture of the grass, due to the B&W conversion, the upward movement created by the hill with the eyes, leading to the star of the show ...a lone tree, striving for greatness. Nice.
Did the tree make it to the top of the hill leaving the others behind? or Did the others crest and descend before the little tree could catch up? An thought inducing photo.
Love how you got them in such a lovely diagonal. Rule of odds, rule of thirds, may even have a golden ratio spiral there ( I need to squint to see that) all combine to make a pleasing landscape image beautiful
