This is still downright fantastic. I didn't notice much ambiance in the quiet verses, but that may be a good thing. I thought it sounded great, so you must've been subtle enough with ambiance to make it work without distraction.
Need more harmony vocals in 2nd chorus, I could just barely tell they were there.
Honestly you could print it as-is. Personally, I could use a tad more electric guitar and a little less acoustic guitar in the power verse. Maybe just a compressor to clamp down on the acoustic to keep those hard strums from sticking out. Maybe a little tiny bit less piano since it's pounding away. And just a little more drums there as well. But that's how I like to hear things, like I said it's a damn fine mix as-is. Those acoustic guitars still sound amazing, as they did before. Very good vocal track as well, I like the added personality to this take.
