It took a while, but I finally got the second video. She's impressive for an amatuer, really. My brother has a band I fool with at times, and she's as good as a lot of people I see that are at gigs the band does. I mean people that get GOOD money for 2 hour sets.
The quality of the sound and video make it hard to get a true sample to give her a really fair judgement. I think the sound quality probably does not do her voice justice, and makes any small errors appear bigger. The stage seemed small and crowded as well, it makes some people claustrophobic.
She has really good range. She tried just a little too hard to use it. She over extends just a little, and it hurts the transition, making it a little choppy, and slightly strained. I'd chalk that up to being a little nervous, and trying a little too hard. All she needs is practice and experience to make it smooth and clean, and she's got the raw talent to get there. She really does have talent and potential. Be careful with song choice, so that you showcase her range without pushing too far.
A good example is Reba McIntire early in her career versus later. Early on, she used her range and quality perfectly, she got all there was tobe had out of it. later, she ended up using a bunch of tricks and overextending, and it killed the range and clarity, along with the power. And she really had it. Dolly Parton is also a great example. She's got the voice and the talent and knowhow to use it. When she gets a good song and SINGS, she's incredible, when she gets an average crappy country song and pushes it, she's no better than okay.
For country tastes, she probably needs to study what the good solo females in country are doing for stage presence. That's a hard thing to get a grip on, but real important, so that she looks like she's comfortable and confident, and enjoying herself. It does figure real big here in Nashville where the country thing is big. Again, what I saw was greatly colored by the fact that she was or at least appeared to be nervous. It makes people make big hand motions, swap the mic from hand to hand, and shuffle their feet and sort of wiggle nervously. She'd be better off to move a little further and more confidently, sort of alternating sections of the crowd to "play to", and holding the mic with one hand, bringing the second hand to it when she is pushing the vocals hard.
She's not making any mistakes that aren't due to nervousness and inexperience, it takes hard work and a long time to get really polished. My brother has been doing lead vocals for his band for 5 years, and is still getting there.
I hope this is what you wanted, and you don't think I'm being hard on her, because I'm not. She is good and she's got potential and is headed in the right direction. I'm just trying to give you a feel for what I know the country talent scouts and judges look for around here in the Nashville area. I hope the tips and pointers help, and don't hurt anyone's feelings, they are not intended to.
Good luck to both of you, I hope she does well, and I hope you both ENJOY it instead of letting it consume you. Have a good time, and the rest will follow.
