this is very good :)

I've got some suggestions, you may ignore this! ^^;
The synth sounds starting around 0:40 could be reduced a lot, because it's a tiny nibble bit too loud~
And add a few melodies? But maybe that's not what you want in this track.
Well, it sure sounds aggressive! =^._.^= ∫

Oh my ears...

Hi!
Creative stuff here, a bit too hard for my taste even. But a very cool track anyway!

After I make a comment here, I'm going to download it just to check it in an audio editor... because my guess is that your mp3 is full of clipping throughout. I know it's hardcore and all, but it seems pushed really far. The parts with less going on, like just bass and drum are very cool... but when there are synths going on, things are so compressed and muddy (and my guess is clipping) that you can hardly enjoy the synths. Okay, around the three minute mark, the synth is pretty audible, so that's good. Nice drop there. I do love hardcore in general, and I can appreciate what you've done here!
