Below, a comment from James Delaney as posted on Tina's You Tube Site. As I agree with everything he says, and I couldn't have put it as well myself, I hope he doesn't mind my adding the comments to this site.
This girl is beyond description. Her skill level, incredible dexterity, technique, discipline, devotion to her passion, maturity and things I can't even find words for are light years ahead of her physical years. I can't even imagine what she'll be capable of in 5-10 years. If she continues at this rate, there won't be another guitarist alive or otherwise that will compare to her. People constantly talk about wanting her to smile and looking bored have a point. This girl is gorgeous and a smile from her would be mesmerizing. Her lack of visible emotion and seriousness is proof to me that she is truly focused and serious about her art. Give the girl a chance, I don't know about you but when I was 16 years old my maturity level was almost non existent. I would wager that she is a perfectionist in everything she does including school work. Straight "A's" wouldn't surprise me. Her parents are right to not divulge her last name She needs to be a teenager and enjoy all the joys and heartbreak of growing up. I'm sure her parents know too well that their little girl is destined to be a world wide celebrity and want to enjoy her before the world takes her away. This girl is a prodigy and a genius, I can only hope I'm still alive to see her perform on stage. God bless her.
