haven't heard the song before, but it isn't bad. I'll crit your singing because that's what you asked for.

You need more confidence in your voice. Sing from your diaphragm more. Google on how to do this. It helps to have a full lungs of air and to sing from your abdominal muscles. It's a little off key too, practice makes perfect though. It's a lot better than I could do:P

A lot of pros do that: if they play a wrong note, they'll hit it again to make it look as if it's intentional. It's called "jazz", aparently.
