The song, the vocals, the percussion, the guitars, top notch and work well together. The intro clarinet is neat, but it's the guitar you hear first, so the clarinet is always secondary...if that makes sense?

But the horns later on don't seem to fit with the song and they overshadow the vocals. I'm not sure what to suggest. The clarinet could work here and there...but some acoustic guitar arpeggios or syncopated strums might help and you might consider some bass solo riffs...I'm not sure if RT's are there for that.

Good luck.
