What everybody else said.

The song works for me. I especially like the musical metaphors:
"played me like a violin"
"life has no more high notes"

there may have been more, but as has been said already, it was difficult to understand your lyrics.

I thought it was a cohesive arrangement... nothing about it sounded forced or contrived to me. The way your guitar playing complemented the melody really added a good effect. That sort of touch just doesn't happen in backing tracks that are totally generated.

To my ears the vocals were not only too quiet, they were also a bit muddy. If you can get more clarity on the vocals it would be a great enhancement to your song.

All in all, I like it a lot!
