You had me for the intro as it promised development but, realistically, it became a series of vamps on the changes.
You need to introduce an element that ties it together like a melodic phrase on one of the instruments that can be repeated at intervals to give a sense of time and forward movement. There were a couple of snippets already within the piece that could be used.
Either that of a mirror ball and chemical enhancement of choice.
