I take it, Bennachie is a mountain top?
And I understand it is a favourite place to go to and witness (and photograph!) the sunrise? And I understand you ALL (i.e. you and all the other photographers up there) KNEW it was going to be a gorgeous sunrise?
To tell you the truth, I quite like the inclusion of the other photographer in your frame. He gives your photo some more definition and depth and scale.
The rolling hills bathed in the orangey light of the early morning sun are nice, but the blown out sky where there is the sun bothers me quite a bit. Makes the photo kind of flat.
