My critique here starts with the fact that the microphone is set a little high, and that throws Hannah a bit when she starts. As a result, she's a little high and a touch screechy early. However, she settles nicely around the 2:00 mark, and she's much better after that.
On the plus side, Hannah's almost always on-key but stiff at the microphone. So with this performance, she's having to get over probably her biggest weakness as a performance. She succeeds with that, and I'm proud of her. As I told my wife, Hannah is ten, and I don't think she's ready yet to cut an album and head out on tour. However, this performance represents a big step for her in terms of her ability to inspire and connect with the audience, and that's not small thing.
