It is interesting - I have seen it before. Her technique is excellent - her ability to go from her lower register to the highest without a "gap" is something that many adult singers struggle with. She is a natural and wonderful talent.
But....there was a young American lass of very similar talent, who was exploited by those who wanted to make money out of her - and she finished up singing bland semi-pop songs, dressed in inappropriate clothes for her age.
It is not just about forcing her voice, but also about dropping her into a high stress scenario when she is so young.
