I'm going to be a little more harsh than the others.
It wasn't good dude. It just wasn't.
However, from 0:35 to 0:52 it was better and in tune.
What I think you should do, is practice singing in a lower key. I'm going to guess that your singing sounded (so much) better at that section because you weren't straining your voice. Sing in a higher key when you build your range.
