I'm not expert but I'll give you my two cents dude.
Intro I like the drums lurking in the background and the synth. I'm a little on the fence about the chord progression during the intro but it does work (I'm just more into the darker sound overall when it comes to this kind of sub-genre) The build up I like a lot the energy really builds well.
The vocal sample choice before the drop sounds a little bit dry, I'd probably add a ton of reverb on it and a delay with a reverse crash after to lead into the main hook.
I like the main hook, the mid-bass sounds are on point, the variation after the first 32 does pick things up and keep it interesting.
The bass sound at 2:14-2:17 I am a HUGE fan off, If you could add more of that type of bass I'd deffinitely be digging it more.
The breakdown sounds clean and does a good job of bringing the energy back in with the low pass drum rise.
Overall I like this a lot (has a very noisia esque feel) I just feel like the one thing that for me is sapping the energy is your first 4 bars of the drop (the bass structure with the 3 hits then synth shot) I think if that was a little more intense at the beginning of every section the energy would pick up a lot!
Mixdown quality overall sounds good through my HS8's.
Keep us updated!
If you could feedback me too dude that would be much appreciated
