Paul,
I like the following things about this song:

1) your vocals are very recognizeable and marketable

2) I liked the reverb added to the vocals.. it really filled it in and added audio interest

3) I liked the used of strings to intensify the mood of the song at those points

4) I really liked the variety you achieved in the percussion... this is usually one of the obvious tipoffs that a song has been produced with some sort of automation. Whatever you did added a layer of realism that appealed to my musical sensibilities.

5) the lyrics are interesting and well-conceived. Your vocals did justice to them

6) piano sounds great.

mild criticisms:
at some point the song started sounding redundant to me. IMO, it would benefit from a more dramatic departure from the rest of the song... maybe even a passage in a different key or raised a half step.

I also think a vocal harmony would add audio interest to the song, if used sparingly


Summary:
Very professional sounding! I liked this songa lot! Keep up the good work!
