(noob here, take with salt)
Technically, most everything is fine...except that I think that the ground is too light. The stark contrast with the ground and the foreground elements somewhat hurts my eyes. I can't put it any better than that (UPDATE: I think the word I am looking for is 'jarring'). Just a tad less brightness/exposure on the ground would do the trick.
Her shirt details look lost in the front, but who really cares, right?
Nice lighting on the foreground subjects, overall tonal balance looks nice (other than that very bright ground), and contrast in the upper third of the shot is really pleasing (mane/blond hair on dark treeline background).
There is a sense of feeling and emotion between the subjects, but to be honest, these types of pictures don't really do it for me.
