Well to me (this is going off the MI clip), it sounds like your trying to turn the song into this over the top opera. Its very wobbly and all over the place and you constantly switch between singing loudly and quitely. Its not that your voice is bad, its powerful and has potential but it sounds as though your trying to sing in a style which you are just not capable of.

So many girls sing Ev songs in opera style and it really doesnt sound cool at all, IMO.
