I had a listen and thought it was pretty good as well. I think my fiance would do anything for me to write a song like that about her! Unfortunately, it will probably never happen. 😛
It sounded really well done. I thought the vocals weren’t clear enough though. It is most likely due to what others say. The effect seems a bit strong, if it’s layered then the dry vocals maybe need to come through, if it’s only the effected vocals, maybe it needs dry a little? Either way, it sounded like it blended too much with the song, making it less clear.
It wouldn’t take much editing, and then I honestly couldn’t critique it negatively any further! Good work!
