i like that a lot, cucumber. some tips:
the beginning could use sort of a whitenoise rushy hit sort of thing, because just having the snares there makes it seem kind of empty.
everything after that and up to 2:05 is good, can't really think of anything to say about that
2:05 to end, i'm thinking the synth you're using here by itself isn't enough, and that it needs some sort of backup melody, synth or bloop, that and it needs to be less repetitive. maybe with some pattern slicing magic, you could mix it up a little bit? throw in some random crazy sounds for a nice complextro feel? maybe make yourself a nice drop there.
also, it sounds more like house to me than hardcore. just saying, lol
