As a fellow Aggro-Musician (and Aggro-Vocalist), I am obliged to listen to this several times and write a review for this track. Lets get the nit-picking sorted out first:

Your Drum Samples/Kit you are using doesn't sound like it's widened enough, it's sort of sounding like it's sitting behind the rest of the track. I would also run your Kick and Snare/Clap combo through some extra Distortion and then run them through some compression straight afterwards to give it some extra colour & sharpness.

Your Supersquare lead starting at 00:49 I would make it slightly louder and I would detune it a little bit more. I'd probably introduce a DeEsser or EQ down the high end on the Sub-Lead/Pad which Starts at 1:05, the high-freq noise is bleeding into the rest of the mix.

Your Bass/Sidechaining between the kicks sounds appropriately brutal but I would consider driving that with some extra bass, other than that it sounds pretty decent.

Anyway, now the above is over, I would like to congratulate you on the generally decent mastering of the track overall and the composition's structure overall. I'm guessing this is your first attempt? If it is then it is certainly better than what my first attempt way! This would sound even better with vocals I would say though. Usually I would offer my services but I am busy with some other projects which require my general vocal-work in plus two or three tracks of my own to sort out. I can offer you a step-by-step tutorial on how to self-do the Aggro Vocals if you have a mic and have afew Plug-ins ready to use for your recordings (whether you can do proper-fry without FX aid or not).

Good job overall, I will be looking out for more aggro-attempts from you in the future. I would personally recommend you should check out these Artists & Tracks for inspiration:
