I love the black and white thing you have going here, Tracy. The image is subtly off-balance, since the limb extends left from the centered tree. It's OK though, becaue the darkness on the right balances it. Now the use of black and white allowed the many grades of shadow to emerge in an image where it would have otherwise have been unnoticeable because of the colors. Your frame job - simple yet sufficient is just right. If the original of this is higher than, say 2MPX it might make a nice poster reframed to vertical.
