Lovely, but you would have needed to chop down those power lines, first, eh?
And indeed, you were there just in time!!! Lovely sunrise. The sky is really pretty - mostly so in the second photo (as there is more sky ).
slight underexposure could have helpod the highlights, but actually they do not reall bother too much on these photos anyway.
the power lines are a bit distracting .. they could be PSed out neatly, but it would take quite some time I am afraid .. you should have cut them before shooting
