Very good shot. I'd say The Woman in Black, but don't take that the wrong way. That's a horror/ghost film and there's nothing horrific or ghostly about this. Serenity and a youthful maturity. I do love it.
I like the pose, and this composition is set up nicely, but i feel the tone of the image is a little too bright. It makes this person with this attire feel a little too out of place. I would consider maybe masking down the background a bit more out of focus, and finding a way to mask out the picnic table, add a vignette and some some darker coloration overtones and the image will really fall in line. Nice work.
