Good good. Elaborate? The parts already there sound to me like a nice bridge/chorus structure. A verse type section for 8 maybe next linking back to the uptempo chorusy section after, really anything goes though, I've already been playing live along to the loop, it's very easy tune to play along with. Maybe, if you haven't already, you could replace, or double up the bassline with a real recorded bass, it really needs something not digital to take that generic, Super Mario(how my youngest daughter described it) sound away. I have a bass and a guitar here, too. I might learn the line and mess about with some live recording tomorrow when the kids go to school. We wouldn't have to remove any tracks, just beef them up a bit with natural instruments. But whatever.
