This girl definitely has "it". Obviously she has the technique down (tone, inflection, head voice, vibratto, etc.), but anyone can learn that; but she's got personality and a beautiful soul in her voice which is something you can't be taught. It's something you have to feel. Even without watching, she clearly has that too. Her voice is great, but the links make me think she's slightly limiting her selection.
In my opinion, she needs to move outside the Pop/Ballad range. As shown in the Dylan cover, she isn't a limited singer and needs to expand the repertoire. I'm going to go out on a limb here and suggest some Musical Theater songs.
I honestly think the Musical Theater genre would be a great fit for her (at least vocally). She has the power and emotion, both of which are needed in this particular brand of music. Now being a theater major, I have multiple songs I believe she would sound great on, and even more that I just would love to hear her sing. However what got my attention is the powerful upper register she presents, both in chest as well as head voice. I don't have a definite opinion on a song yet but I'm going to type out my thought process and I should have an answer by the end of this post.
First song that comes to mind is a song from Les Miserables. The performer in the video is also known for her role in Miss Saigon. I don't particularly like this version; if you look up the Original London Cast version, I prefer that one much more to this one. Either way, this song requires a strong emotion from this girl who sings of a man she loves but knows she will never have. This song does not have insane belting like some more modern shows, but does take the voice to levels that are both impressive and emotional, both I believe our original singer can achieve. Take a look at On My Own from Les Miserables:

Next up is a song which would be a little bit harder to learn and would actually be a fun little film project in addition to a vocal adventure. From the gothic musical thriller Jekyll & Hyde is a song of two women who represent Good and Evil, much like Jekyll and Hyde, each one appealing to those respective women. It is intended to be a duet, but there is a version of this song where Linda Eder actually records her voice on multiple tracks, singing both parts of this song, and it sounds wonderful. I believe this song is very beautiful because of the sweeping melodies that carry throughout, but it is indeed a very vocally demanding song. If you're up for the challenge, In His Eyes from Jekyll & Hyde:

next up is one of my favorite songs. The song is simply about a person who cares and is actually gender neutral; I've auditioned with this song on more than one occasion. While it's not a difficult song, it's quite beautiful and has plenty of room for interpretation. There's no real story as the show it's from is simply a compilation of songs rather than a true show. Enjoy the song Anytime (I Am There) from Elegies:

fourth, and finally, is one of the most moving and powerful songs I know of from my personal favorite piece of theater, Ragtime: The Musical. The song is written for a black woman but I am quite sure our singer here is capable of this task. I've had multiple friends sing this at recitals, cabarets, performances, etc. and it never fails to bring down the house and even leave the more emotional ones in the audience with wet eyes. The song is about a mother who attempted to abandon her child as she's single and alone and believes the father has left her forever. There's no more introduction I can think of, so here's Your Daddy's Son from Ragtime: The Musical:

anyway, those are 4 songs, i think she should definitely take a look at. If she's feeling adventurous, definitely the last one. If not, the first one. The other two are possibilities but of course this is just all my opinion. Do with it what you will =P
Congrats on having such a fantastic talent and I wish you success in whatever path you choose to take.
