First off, neat idea! +1 for complexity increase, just like life. Sorry, kids!
And as it got more complicated with more awesome parts, your mix never got muddy or imbalanced or incoherent. Just NOT like life.
So, for true realism, I suggest by the fourth or fifth matchstick, boost 300hz by about 10db with a wide q, and if your matchstick gets married, a boost up around 3-5000mhz, something sweet but shrill, ought to do the trick.
Or maybe it's better the way you have it now - yeah just keep it the way it is, it's pretty darn perfect.
cheers,
