I have to agree with @KurtS on this I am not sure you need drums on this at all it distracts rather than enhances. That little HH tapping is quite irritating.
To me progressive means it is is not mindless pop, it means someone has taken the time to construct a real well thought out piece with more than three chords, or not just I, IV, V.
I like this is a piece worth listening too, nicely done sir.
