Nr 3 in monochrome would be an absolute winner! The circular effect of standing there is immediately obvious, but it also depicts that more subtle idea that nature is neither chaos, nor structure... Good capture!
Good set. 1 and 3 are my favorites.
John, those slides are great. You should contact the local government and see if they want a copy for their historical records.As for the others that suggesting cropping, hmmm, not sure... I like the way the trunk leads into the scene.
