well honestly i'm not hearing anything that i'm immediately against - this is pretty damn nice.
the percussion and the arrangement are really nice and tight especially - i feel like you just want a pat on the back ahahah

maybe it's a little dry - even though i get that you seem to be going for a more minimal vibe.
i'd be fine with this song being the way it is really, although i agree some kind of bass on top of the sub could be really nice. maybe the piano could be more prominent in places? in some places maybe like a chopped up music box or bell could be cool??
