Man, all this thing needs is a British narrator and I think you'd have the perfect opening to an old-timey style series!
I really love the choice of instruments, but what surprised me the most was how much the graininess did for the piece! I do not think it would work out nearly as well as it does if it didn't sound like it came out of an old gramophone. It actually gave me tingles, I kid you not.
As usual, the style is on point, and when a par-for-the-course is this good, I think you should be quite proud. :)
