rpt - you and I have the same eye for composition ! Your crop is how we originally produced the pic. However the rock in the foreground is oof, and my partner in Building Panoramics has a real dislike for oof foregrounds ( bearing in mind our commercial pictures are buildings ), so we settled on taking it out.
When I took this picture I was using the standard screen in the 5D with an 85mm and I didn't intend the closest rock to be oof. Since then I have the manual focus screen and it is much better for both manual focus and judging subtle depth of field. Personally I think subtle oof foreground can add depth, but maybe in this case it looks like a mistake.
For those who like more symmetrical compositions I can accommodate !

Thanks for the feedback from everyone, I joined CR because it's a forum where the members are polite and courteous, and judging by many of the pictures posted - very talented ! So I appreciate the comments.
