It's still good, arguably better? But you need to have a few cocktails, or whatever your preferred alteration is, and retrack the vox, and sing it with attitude... Like you have the biggest "mic" in the room. You have to feel it, and make everyone else believe it's true.
And I understand it's probably a tribute (not familiar w/the original) but I would echo some of the lead vox parts after they happen? The vox definitely need more energy. You may could do it in the mix? I.e., double w/a slight delay, compress, slapback? There are lots of techniques. The guitars and everything else sound great to me. And the vocal performance isn't bad? It's just not blowing my skirt up? And I feel like it should on this kind of tune?
And the guitars seemed to "gel" once the song got going? Early on, the one in my left ear seemed a little early on the attack? (only slightly) The one in my right ear seemed to be on throughout.
These are minor observations (except the vocals :-) Again, I like what you've done? But I would make it more "banging..." A tune like this needs that vox "in your face." However, please keep in mind, I am not a mix master, and sometimes ****ed when it comes to this aspect... I am merely offering my honest opinion because I respect you as a forum member, and musician. You should blend my input with others. (however also keep in mind that some people only blow smoke? And will never give an honest opinion)
That was "re" and rhymes w/popTARTed. But the SW ****'ed it out.
