I have to agree, the vocals seem to be pretty tricky, I get the feeling that he is not really singing in tune all the time and I am also not fan on the vocal tone. That said a touch of room verb on the vocal would help, because at the moment it sounds like a dry track. I would also bring up the main guitar as it is often by itself and bring down the other instruments so the dont poke out as much.
I've done some things, on the vocals, and mainly also turning it down quite a bit. As I was mixing it, I didn't quite realize how freaking loud it was.
I like this new version better, but hey that's just me.
