Nice message... truth!
On the song.... I'd look at a redo now that you have learned a few things. I agree with the nits mentioned above. No need to rehash them.
The song was fairly short. But yeah, it's worth taking that one back to the studio and start recording from scratch to do a better version now that a few years have passed. I did that very thing on Missing Person recently and .... what a difference a few years made.
