hmmm, now if i was a woman out for a walk at that time and a guy stopped behind me with a camera i'd think "stalker" lol.. so i'm guessing this is staged and not candid.
The chances of two people being at the same spot at such an early hour and the shot not being posed seems a little slim to me. Nice idea though, I like the backlighting on her hair. Lens flare is a bit distracting.
