Intro : Liking the build up on this man ! elements sit nicely along the spectrum (like the idea of using the low pass filter on the drums I'm a sucker for that too) - I'm a fan of all the little musical elements aswell I think you've amassed all you need to really round this track off.
Drums : these do feel a bit thin and static (as in stiff) - I think the kick is lacking a bit in the low end (I'd deffinitely recommend layering these drums) - something like a ZERO G Jungle pack with the mid to low cut out will give the drums a lot more of a rolling presence (a shuffle would deffo go down well aswell) - I don't know if it's just me but I feel like the hats are being panned to my left speaker.
Breakdown : structure wise I think you have everything down well it's just the drums that are holding this track back
Sub: I'm not getting any sub throughout the track (mid bass works well though although I might advise to low pass it a little bit and layer a sub under (3OSC Sine) - or any sign wave would go well)
to add: If it was me personally man I'd just work on those drums - sub - + maybe add a vocal in and take down the volume on that stringish instrument that comes in and it'll be on it's way for sure. good stuff !
If you could feedback me too man that would be great
