How's my singing? Best answer, 10 points! x?

Don't take singing lessons, only do it as a bit of fun :)
Just wondering what you thought? Constructive criticism welcome :)
Sang some of Fallin', by Alicia Keys.
No I don't want to pursue this as a career, I'm going into the Army in
September, so once again this is nothing serious, just a bit of fun.
