I saw the original set and didn't comment. These have been edited in such a way as to have some real "verve". I think her skin tone and hair color in the first shot looks a bit too-light in value, compared with the beautiful saturation in the second shot. You've made a remarkable transformation between the originals and these. As senior portraits, this trio goes a long way in capturing your sister's youthful beauty and appearance; in the future both near and long-term, people will be able to look at these photos and get a real feel for what your sister looked liked as a senior,so you've succeeded in making good senior portraits. Good job!
