Yup, the recording was great to start with and the vocals improves it further still. Awesome job.
If you can forgive me for offering some criticism though, I did cringe a bit at the Afrikaans pronunciation (but probably nothing like the cringe of every Zulu, Xhosa and Pedi at my pronunciation of the first half). Also, the phrase that starts at 0:52 "O se boloke" should have the "O" on a half note plus an eighth (minim plus quaver) as opposed to only a half note.
The first line here shows what the metre should be while the bottom line shows what the vocals in your recording does.
Please don't take this as negative criticism though. I really do love the recording. In fact, it may well be the best recording I've heard of our anthem so far. The vocals have a lovely timbre to it.
