Tim, your pictures are amazing; I just love the second at post #89, and the one at post #92, both are very inspiring.
Now, the first one at post #89... please do not get mad at me, I know you have a very refined technique, and I am completely confident the camera was perfectly horizontal; but it looks like falling. The only visual reference I have is the shoreline, those trees and their branches go in every direction; and when I see that photograph, my mind can stop screaming "falling horizon". If this photograph was mine, even if I knew it was a perspective thing, I would have 'corrected' it; perhaps just as a favour to the viewer, or perhaps just to get rid of these pesky comments at the forums.
