It's a pretty cool track. Music is great.
Although I don't care for the subject matter that much, the writing itself is pretty good, and a highly creditable effort for a nineteen year old.
The performance is fine. Sometimes the ends of phrases sound a bit insecure, as if she wasn't quite sure that she was going to hit the right note.
I wouldn't mind hearing a bit more vocal variation to add more interest to the vocal line. For example, there are parts that could almost be spoken and pulled back, which would give greater emphasis to the chorus.
