In my view, this track has really great potential. I thought the slight distortion on the vocal (and most of the other instruments) was a good move, and the whole thing had a really enjoyable vibe.
I agree with most of the comments that the vocals weren't bad, and could be developed to suit the final cut of the track. It seemed to my ears that the vocal note selection on the first lines of the verses was a stumbling block, may be worth reviewing the melody a bit there. Maybe.
As you said, the long fade was a mistake, so no criticism there, it didn't work for me personally.
But overall, like wot I sed at the start, this is a track worth persevering with, as I think it has excellent potential, and should appeal to a wide audience!
