Her stage presence is a bit off. She doesn't connect with the audience like she should. There was literally someone dying when she was about to perform Firework and she looked at it and continued with what she had in her mind before the show even started. Her dancing and vocals need work as well. Her voice is OK, but she needs a technique to control her voice. It's all over the place.
WOA and POM are the best imo. I'm done. Roar is a huge borefest to me.
