Nice piece, but in my case the reaction was the opposite: I loved the beginning and when the drop came it didn't work for me. I wanted the intro to evolve.
I would say that Philip Glass as a representative of minimal music is pretty outdated. I say this cautiously, since one doesn't need to necessarily draw an evolutionary narrative here.
But these days we have way more ways to evolve a texture like that, whereas he had to rely on orchestral means only. And so a minimal loop like the one you mention as your inspiration or even your own intro could be evolved into a really fascinating piece, by mostly focusing on the DSP aspect of it. There could also be certain sub-melodic elements, like phase shifting, changing scales or otherwise manipulating the midi/audio information that doesn't involve changing the relationship between the notes themselves.
It's always very difficult to suggest something, especially when you're trying to present a whole new world through just several examples, but I decided to pick two releases by Steve Roach that demonstrate how a sequence might work with no drops whatsoever.
