I'd say that's a pretty fair representation of her performance on the tour.
However, I did find her singing voice to be quite strange. One minute she seemed to be out of breath, and the next she was belting the notes wonderfully. This breathiness was especially notable during Light My Candle, where she sang "Would you li(gasp)ght my candle?" Like I said, when she belted at the end of Out Tonight, it sounded great, and I wondered where that singing went during other moments.
Her acting and dancing, though, were great, and she actually looked 19! (Imagine that...)
