Well sung Tony. The guitar sounds really good/well recorded. This is exceptional and the mix is like fine chocolate... My only change if I could make one would be to pull those background vox down just a touch, or maybe just have a master vocal bus where you send the lead and back-up and limit all of it and send it to the mains, this is how I usually tackle it when I have something with the lead and several backing tracks. It's easier for me than trying to ride the faders. i.e., LV to the Voc master, BV to the BV Bus, treat and pan as needed, send to the Voc master, send all instruments to the instrument master, and send both of those sub masters to the mains. Then you can compress and limit the two sub-masters, and then apply the finishing touches on the mains. No one told me to do this, it's just something I came up with through trial and error. However, there are many ways to skin the cat ;-) And you're a pretty good cat skinner ;-) Much better than me and most!
