Heya! Your voice is good, but I don't think it's best if you audition with this song.. For this song, you made your voice higher than it should have been sang, and it would have been fine if you had control with your voice, but it was obvious that you were struggling with that. I suggest a song like something that fits your range, without you having to go high or low with your voice trembling. Just some advice. And always drink water to have a clearer range and so that you won't have voice cracks! :)
