I also agree with the notion that nothing new really happens in the drop. Your mid range bass could really use some punch in the sub region. Right now it seems very top heavy. I'd layer a sub bass below your current one, or tweak the current sound. (sometimes the latter is tricky, so layering might be easier)
Also if you want something to "happen" in the drop, you could always use some pads/chords to make things pop, instead of resorting to sort of technical production tricks.
