Takes balls to cover this.... I think most of the appeal of the original is the big powerful drumming that drives the song forward, but it sounds like you're struggling a bit here if i'm honest

Not that I expect you to replicate john bonham, but I think you should go back and give the drums some attention first before doing anything else.....fix the timing issues, and add some feel/swing/power. I like the spirit behind your effort thought -- it definitely has potential.
"Bonham was a master of laying back in the pocket, meaning he struck his snare drum a fraction of a second after the strict metronomic center of beats 2 and 4"
