dude this is sweet, sub sounds fine to me. I agree with the kick and snare not being punchy enough. The mix sounds spot on in the beginning, I'd say maybe a bit less so in the drop but it's not bad by any means, just sounds a bit less controlled during the drop. Not sure how to help you there though, maybe reduce the growls by a db or two or compress? I thought the buildup was pretty good, could just use some automation and/or fade in on the kicks. Cool ideas though, man! I love the break and little fill right before the drop.
Heyo,
Sub bass is fine. Kick is too weak and not punchy enough, Snare too. Try to sidechain more if you like them tho. Yes, you definitely need more sidechain on basically everything. Also to make the second drop more intersting, try changing the midi or chop more those basses. 
Although, good track. 
Thanks for the feedback guys!

I agree about the kick and snare being not punchy enough in the drop, in the intro I like the way it sound, not too hard to give that "chill" feeling

Also don't worry for the others drop, I have some ideas atm but in this version, it's all ctrl c ctrl v haha
I'll give it a try for the sidechain too

Didn't thought about that for
