Falsetto is a felony
Well, it served most Motown artists quite well, to name but a few.
Nothing special besides that she is cute and 14.
She does have a good voice. Regardless of how poor the songs are, or how much she imitates the style of the singers whose songs she's performing, she herself has a good 'instrument'.
I watched two videos of her on YouTube, one from last year and another from this year. In the earlier one you can hear how the lower end of the voice was undeveloped. She does have a big range but her natural range is probably mezzo-soprano and she sounds weak when she forces the lower end. A year later, you can see how she's been having singing lessons and the lower end has developed a lot.
She seems like a nice, unaffected little thing. Good luck to her.
As for her English accent, she sounds fairly American to me.
Instead of teaching survival language, the idiots make you read poetry.
I remember reading Maupassant in French and nearly dying of boredom but we got a really thorough grounding in grammar and vocab and we certainly had more than enough French to order food, ask directions etc. What people tend to lack is not so much the language as the confidence to use it.
