Her vocals were good. She's far better when being less choreographed and just focusing on her vocals -- at least for now until she gets more comfortable around the stage and maybe gets some lessons to loosen up a bit. I don't think people understand how much of a tough adjustment it must be to go from spending her whole life performing with 2 completely hyperactive guys, and mostly standing/walking around and just singing.
She also needs to stop with saying things like "here comes that drop, guys!"

It just doesn't sound right.
