This is an excellent image, from the choice of subject (the tree), additional elements (the bench and silhouette), composition, B&W processing, square crop, and tones. The dark corner makes it a bit unbalanced, but maybe that was your intention.
a 9, i like this image even better w/o bench and person to emphasize the tree!!!!! my eye doesnt stay focused on the central point of the tree, but, if someone were sitting on the bench too, being said 'good bye too', then WOW
