Souds good but I would like to hear some good tube vibe on the guitars. The lead vox is well done.
The lead guitar track is a little thin but as you said you wanted to do that over. Well played though. I assume you are running through effects, DI or with just a pre-amp? The drive is there, but the thickness is lacking. What's your rig?
35 years ago I would have offered to do your high harmonies for you... but that's because back then I actually could have done it. Those days are gone.
