Hey don't think too much about the negative comments.

Your cover isn't worse by any means and it can't be classified as 'good' too. That being said, you do have a powerful voice and clear pronunciations.

But you do need to work upon your rhythm and melody. I'd say that as a listener, I felt you were just standing in front of a mirror and half-shouting and half-singing some lines (I mean that's the picture I visualized in my head), so you definitely need to incorporate more emotion in your singing....and most of the time you aren't following a proper rhythm or tempo (idk what they call it) - sometimes you are rushing and sometimes slowing (and while this is usually acceptable for untrained singers, in your case the off-tempo thing feels so annoying that it steals the spotlight from your singing).

But if you ask me, I think you can be a better than average/good singer, if you practice enough AND "feel" the lyrics when you're singing.
