Nice angle were you sitting there or something like that? I think even so it turned out pretty well and it even seems on purpose. I like the light very much. It's like if she is waiting for someone in a somewhat desertic place.
i like the light and filter but personally i wouldve taken the shot a lil closer. more than enough floor is showing so by getting closer i'll take away some of that empty space and put more imphases on the girl and the stairs.
