Most people don't usually sound like the record...
EDIT: I think she sounds great! I guess that's just my opinion though...
But to me her tone sounds totally different (if you ignore the backing track she's singing over the whole time). People like Katy, Rihanna etc. might not sound pitch perfect but their tone sounds the same.
Also I think she is getting really better but I think her stage presence has room for improvement. Some of those moves were kind, eh bad. The choreographed stuff was good but when she went out on her own it was blah. But I always see artists improve in their performances they more they perform. I expect this from Natalia as well because she was already been improving.
She has improved. But after some minutes she loses it again... She run out of breath and she really has to step up game if she wants to reach superstar. She has the music but not the performances. Work on it!
I love her though!!!
