Aww, I like it. I especially like the catchy part that is turned into a musical riff toward the end. It's high but not too high, she doesn't sound like she's pushing herself, it sounds more natural and pretty.
I am getting a little tired of her staccato breaks (the pointed, dun dun dun dun dun parts)though. Well, in this song it sounds a little unprofessional compared to the rest of the song and I think it'd sound smoother with a touch of sustain.
