There are two avenues of critique. Most people here seem to be critiquing the artistic value. On that level, yes, she's basically a generic, less refined Taylor Swift. There's potential there. But the competition is tough because the degree of difficulty is low. It will take plenty of both hard work and luck to get mainstream success that way (seems like that's the type you're talking about, "the music industry").
The song structure is generic, the lyrics need refinement, the voice needs a little work (though mostly pleasant), and is just generally very boring. The good news is that from an artistic level she's much closer to Taylor Swift than she is in terms of success.
In terms of business, she can wait around and try to land a record deal, doing mainly promo shows, youtube vids and demos. But honestly, she should just get out and play shows wherever she can (teen centers, girl scout events, talent shows whatever). She'll get better and build a fan base. Fans attract more fans at any level. The first two links I'm guessing are original songs and both have nearly the same number of views (~350). That makes me think she has roughly the same people watching both and that her fans base right now is extremely small. So I'm thinking she's probably extremely local, like hometown local, right now. Start there and branch out as opportunities arise. Her covers have about double the views from what I saw and that should be expected. Keep doing the covers too. You never know when she might absolutely nail the right song at the right time.
When the time comes to record a new demo, make sure the quality is top notch (shouldn't be too hard or expensive these days). Don't be afraid to hire a professional songwriter (buy a song) for one or two tracks.
