George,

Yes indeed. That is a fantastic shot, and a very encouraging image. I'm a
believer for the double arm! Great tracking.

You know, I think the problems you mentioned in shooting this image, can
actually be thought of as strengths here.

The softness lent by the lens and smoky atmosphere, to me convey an extra
sense of majesty. I see the tips of the trees in the bottom right corner.
Imagine a second shot with more of the trees framing the soft field. That
would be just, wow!
