Okay . . . I decided to go for a search . . . and I found the site and the song.
You say you are not a singer, that you are a songwriter, and you want comments on your home produced song.
Strangely, it is your voice that I like best of all. I accept the limitations that it has at the moment . . . for example you run out of breath quickly. But I kinda like its timbre, and it would be interesting to here you try something that was lyrically darker and more desolate.
The song "Forever and a day" doesn't do much for me I'm afraid. I appreciate the sentiment behind it, but you've delved too deeply into the cupboard of cliches for my liking.
The production has some musically interesting things, but you have a fair bit of work ahead of you to make this gel. There are two major points of disconnect. The first is between the voice and the general backing: there's no sense of them belonging together. The voice is too far forward, the backing is too far back. I acknowledge that the mix ensures that the vocals are heard. The second point of disconnect is between the vaguely guitar-sounding instrument and the backing. The solo bits sound too artificial, and don't mesh properly with anything else. Additionally there are some timing problems here and there.
If you see yourself as a writer, and you want to be recognised as such, maybe another approach could be to keep the backing as plain as possible; just a piano or a guitar, so that it has at least a neutral effect on the song. That way the lyrical and melodic quality can be judged without being contaminated by background distractions.
