great song, Rob, and I can deffo hear Mark's touch on this. I enjoyed it's harkening back to the 70s...got a little "Tiny Dancer" off of it here and there before the chorus.
Some crits (as always, take them as they come):
-vocals are buried a bit, as per Herb and Tim. I think the reverb you are using needs a huge cut from the bottom end (maybe 500hz or higher)
-the placement of the dobro (?) in the intro could be moved off to the side so it doesn't clash with the acoustics (which are too loud the entire tune and require more HPFing)
-the swells at :35 are terrific
-there is a snare hit at 1:28 that sounds completely different from the rest of the hits and kinda interrupts the feel
-the string things at :50-53 are a great idea but they are too crisp: I would cut the highs pretty significantly to give them some distance
-the string riff at 1:19 sounds keyboard-y
-snare has little presence...it kinda comes and goes...needs more compression and some reverb to de-mono-ize it
-agree there is too much going on in the lead portion...I would get rid of some elements or do some drastic eq cuts if you want to leave them all in, and/or do some hard panning to make room for the lead
-the cymbals are too loud and in your face...I would do a lot of HPF on them to just make them fit
All in all, a stellar outing.
