Man I really appreciate that, that's like my favorite compliment I've ever received about any of my music. I've always been a big fan of "Land Down Under". Ever heard the band B Foundation's version of it? It's pretty fuckin sweet. But anyway, nice work on yours. I don't think there's anything wrong with your vocal ability, but I would say that the mixing for your vocals is a bit too muddy or distorted. It seems your guitar track, which sounds nice, is competing for the same space as the vocals, like perhaps boosting some of the high end of the vocals would help. Again though, that's just messing with knobs and shit, the ability is there though!
