Thanks for the feedback. You nailed the big issues which reflect why I waited 6 months to post this.
Dave, Terry: for brightness, I am still trying to find the balance between reality and the way I remember it. The stones are a little brighter when you look directly it them, and maybe it enhances the modest magicality of the scene.
Brandt, yes this looks like two pictures. I have indeed spent some time creeping about getting just the stones. I'll try again this summer. This is the best of what I have so far.
Thanks for the links to other stone art. David, the CO video is exceptional both for the stones and the quality of the video.
