Thanks, Todd, your advice is well noted. I may actually bounce the lead back and forth a little, too.
Glad you enjoyed it, too. I know what you mean about transparency. I tried to make a big sound with as few instruments as possible which I think is key to keeping it alive. I threw out a lot of secondary events as I saw how well the basic tracks were shaping up, and I abandoned all effects whatsoever, save a teaspoon of reverb in a couple of places.
It's the best way for me to work anyway, having a rather short attention span I like to keep things moving or I lose steam on a project or kill it with overwork.
I was afraid if I ran the lead down the middle it would cancel out too many sounds that held together when separated. But a little presence on the right would probably make it more comfortable, or L-R movement.
Agreed, the Carpenters' production was something to learn from. Talk about presence, too! They were brilliant in the studio. I'm also interested in George Martin's early work creating stereo mixes that worked well when perceived in mono.
How do we define protest music, anyway? If it's anti-war but doesn't make anyone mad, then so what. If we go with the notion that protest music is that which gets us old farts' knickers in a twist, then I guess there's still lots of it out there, even unintentionally

so we'd be writing counter-protest music?
