I meant nothing detrimental when I mentioned the "Lines" comparison. It was just vaguely similar that's all. Your song stands on it's own for me.
I've written over 200 songs and I'd be very surprised if there's an original chord progression to found in any of them!!

I can remember way back when, learning my first four chords on guitar.
They were G Em C D.
Instantly I could play probably fifty classic songs from Love Hurts to Every Breath You Take without even changing the order!!
Like Noel says, it's what you do with them.
