#1 and #2 do nothing for me.. too cliche / bad backgrounds / other.
#3 could have been nice if you had capitalized on that beautiful field, and used it frame your model. Facing the camera.... not just her back! Some vertical portraits of her, smiling, laughing, etc.. with that in the foreground / background with some softness from proper use of DOF. Maybe some closeups of her, showing those gorgeous eyes...
So much you could have done with this! Did you? Do you have other, hopefully better images to post?? Hopefully with reflectors and / or fill flash?
