this is a cool concept/idea!
I also love stereo panning, it's just so cool to me, even tho it's a very simple concept. The tonal changes are very hard to spot!
I feel like there's lots of room for more in this track. If someone wanted to remix, or add to it, I feel there is potential for further composition. A solo perhaps, and some other sounds, especially high percussion sounds like hi hats and/or chimes/bells would compliment nicely, I think!
I'm gonna put this one in my list
