My first impression is that your voice used on the verse has a nice tonality and you know how to use it effectively. Sounds great.
The chorus, "the world...", seems like it could use a bit more lo-cut to de-emphasize the fat lo-mids as that's where the tuning could be better.
If you really like the fat sound of the chorus part then I'd try a few re takes or run it thru Melodyne or something like that to get the tuning tighter.
Other wise... overall it sounds pretty good.
