Vocals are pretty pro, nice ballad.
For me, the bass was too hot. I'd back it off a bit, and I think it might be overcompressed? over limited? I know you want that nice loooong bass sustain, but it also accentuates the finger movement of the initial attack.
My guess is, 99% of people wont care about the bass, sustain, compression - they'll just think "what a pretty song!" which it most certainly is.
cheers,
