I think we have a daughter here, the resemblance is right on... excellent! Pretty young woman. Just a tad too far to the left in the composition. She has beautiful hair- let's show that. The rock is too heavy being where it is and dominates the weight of the photo- it's intrusive. (I was just playing with the clone brush to knock down the rock with vegetation and the burning tool to darken the background. I thought it looked much better.) I think more of the dress and less of the background would be advantageous. Maybe a bit of vignetting would help here too. Exaggerated good posture would be helpful- that is, straighten up the back although it may feel unnatural. Turn the person ever-so-slightly more toward the camera. After all that I still think it's a solid photo.
