Very cool! Nicely seen and captured
Did you try centering the line making it symmetrical as another option? I think it is a composition that works rather rarely but I think this may be one of those rare times...
Thanks everyone! Yes, it's a straight shot, taken with a 100 macro, hence there's some compression, which adds to the confusion. I like it with the foreground tree off to one side and the background occupying more of the image, although it might work centered as well.
