There are billiant moments in your song!!! I think sometimes you lost control of your voice because you are so passionated when you are singing!!! You are felling the song! After practicing you are going to control emotions better. I remember when I started taking some singing classes and sometimes I cannot sing because I started to cry in the middle of the song..OMG hahaha... Pure emotion and it is great how that make us feel when we are singing <3
