The lyric has a nice, bouncy feel to it and I'm interested in hearing it set to music. I think it could be very catchy!
You introduced the piece with these words, "A love song based loosely on the standard blues format". So, I was expecting a simple love song, and the lyric seemed to support that with a couple mysterious inconsistencies. I had no idea the couple in the song were not necessarily already together and maybe even would never be. From the beginning, it sounded like an established relationship to me. I didn't "get it" until you mentioned (in a later post), "The reason why I put the northern wind verse at the end was because it added a bit of mystery, would they get together or not?"
Anyway, once I understood that, the unstable elements of the song made sense and it was all okay. Without the explanations, though, it's fairly likely I never would have gotten it. So, speaking for the more dense individuals in the world, it's too obscure for us. That doesn't mean anything should be changed, though. Indeed, we need to be challenged so we think more. Eventually, in a conversation with someone, I might have figured it out. I'd like to think so.
As others have indicated, the images in the song stand out. As I read the words, I see pictures in my mind. A good job of "showing" rather than "telling".
