As a professional musician and father of a very talented teenage daughter, I can't say I'm impressed with this girl and her overproduced "look at me !" video. The music is quite uninspired, generic, and even crude, as is her dancing. She's not graceful or even well-dressed enough to present anything more than some overenthusiastic hair flipping. The money spent on that vid would be better put towards an education, whether it be in music, dance or academic.
Sorry to crucify the post, just my opinion. If you're into excellent girl violinists (non-classical) check out Elana James from the Hot Club of Cowtown.
