I reckon a crash or some white noise on the very first beat would be nice, maybe bring the stuff backward from the 16 bar point to give you additional ambient layers.
Hi hats or percussion from the start of the intro might fill your tune up more too.
I reckon those bass stabs just before the drop could be played on their own in isolation for extra impact like how Emperor does on "She Said":
Some kind of riser before the drop might be nice even if just white noise.
The bass sounds really cool, not sure if it works with the piano on the drop.
Have fun and be creative with drum fills and adding and taking away drums and other elements for better progression.
