What a great performance! At parts I could tell she was nervous, but she did a really great job! It threw me off that it was deeper than the original at first, but it didn't bother me by the end.
I was expecting a way better performance tbh. Her dancing was so Girlfriend-Avrilish and her vocals average (except for that falsetto -I guess- at the end).
She reminds me of a really really really nervous Katy/Kesha hybrid as a performer, but she can get a lot better than that imo.
