I agree with Shikimo on basically everything he said:
Snare at beginning is a little rough. Sounds very High-End heavy (same with the hi-hats I think). I like the triplets, but maybe change the synth thats playing them.
Kick doesn't stand out during the drop, and maybe there should be a kick at some point in the intro, maybe around 0:19. The first riser into the breakdown has a little bit too much High-End as well.
The Breakdown rocks. I love the atmosphere. The reverb-snare, shaker effects, it's all really really good. At around 1:09 it gets a little muddy, but that's good on some extent since it's rising. I do like the vocal sample that goes on, but for some reason it sounds awkward right at the beginning. You do get used to it though and I do enjoy it haha.
The drop needs a ton of side-chaining. All the sounds are fighting for the same space it seems, and nothing is really coming through besides whatever is loudest... which isn't necessarily good haha.
Not a bad track though I really do like it, has a ton of "Dillon Francis-esque" attributes

Also if that is your friend's voice recording from a phone, keep it: it's amazing haha.
