Mike, there are lots of great things about this song that tells me it has tremendous potential. You have a great hook and good use of background harmonies, for example. I hear a lot more arrangement issues though than mix issues. I'll share some, if you don't mind...
I'm not sure the purpose of section 1:20-1:33. You've ended the great chorus melody and are ready for transition into the next verse, but I think this part of the song makes the monotony of the strumming acoustics overbearing. To replace the "so long ago" vocals, I would come up with a lead instrument melody instead. In other words, it's a sort of "dead air" where not much is happening, and it's too early in the song for it. Using it at 3:10, near the end, fits much better.
Also, ending 1:57 with "long" way before the end of that measure leaves another blank space that loses the listeners attention and got me a little lost in the arrangement. Picking up into the solo, I'd much rather hear the energy of the vocals carry me into the solo rather than fade away into the next section. That seems to be the only line in that song that ends so early in the measure. Your vocal melodies are very good, when you use them, but too often I thought that lines were cut short and momentum was lost. 2:52 is another example... add a couple words after "friends I miss"; the vocals seem to abruptly end otherwise.
Surely, it's all personal preference. But my opinion is that with a few arrangement considerations and changes, the song would command more attention and the flow would be more consistent. Honestly, I thought the mix was very good. I love the delayed guitar a lot. Gives it a whole desperate and "longing" vibe. Very nice man
