What is your goal with the song? Pitch to artists? Film/TV? Your own CDs and gigs? That's critical. (Posting the listing that screener was reviewing for would help)...
The assumption we make here is you are trying to write for commercial success from the POV of pitching to artists or film/TV. If you are writing for your own CDs, gigs, etc, you have way more leeway though some of the so called rules still apply. You want an audience to resonate with what you are saying.
The general rule of thumb for commercial songwriting, especially for newcomers, is "If you have to explain it hard, it's not working"...
