The concept is really good! The choices for instrumentation are very clever.
My only issue is that sometimes the percussion/rhythm section seems inconsistent, like switching from a steady meter to a syncopated one at random intervals. I think it might be a result of looping the guitar/percussion just a tad off the beat, which creates a sort of 'skip'.
I noticed that too. I was playing around with the timing and I think I got it right on a newer version (not uploaded yet). Actually, would you mind if I sent the new version to you so I can borrow your ears to see if I fixed it?
