Hi back at you,
I don’t know the Harrison plugin but I do know about music creation. I like the chord progression with its interesting changes. The lead works well with it but I feel you need some variations during the repeat sections to build more interest. These could be with a second line over the top or a variation in tone or both, of course.
The recording is a bit tinny, the drums in particular. I get they work like a click track for you but the sounds need a lot more depth in quality. I sense there is a bass there, too.
Keep developing your ideas, very worthwhile.
Jonathan
