My take on this comes from a songwriting perspective...I don't think the song really takes off until you get to the first instrumental section...the chord changes behind that part are very good...I kept thinking how you could have made a very good melody over those chords and then kicked into the part you have after the instrumental...
to my ears that would improve this because I didn't lock into any of it before the instrumental break. It all came together after that and sounded very good. Very well recorded, too :)
