Since you asked for, I will only address mixing for now:
  • there's humming from the bass amp audible during quieter passages
  • the bass has a lot of low end, which might be a problem with some playback systems
  • the snare could have a bit more body
  • I remember Terry's voice being a little brighter than yours, so you might need to duck the organ a little when he sings


Overall, the song sounds pretty good already [Linked Image - Only viewable when logged in]
