I think this is a nice image. A few thoughts which would take it from nice to really nice: (1) Fill light is needed to bring out the detail in her face; (2) While the tangle of branches behind the subject is interesting, I feel they're competing for the viewer's attention. I would consider moving her away from that area; (3) She's rather too centered for my taste. A crop of some of the space on the left side of the image would improve things I think. You might also consider a vertical (Portrait) orientation; and (4) remember to level in post.
