Her face expression should be in highlights... herself or focus on reflection. But anyway i like the feeling of this photo, makes we wonder if she's thinking of a place where she's going or a person she's going to meet/left behind. :)
I like the idea very much - a deer from forest sneaks out from woods to see "the another world" ...
Maybe the composition might be better - i'd prefer that electric pole to be aside from the lady :)
