I enjoyed it; the sub is excellent. I thought it was interesting how you only played a clip of a drum break, almost as an effect or incidental sample. That was pretty cool, but I did want to hear the break play out against the song at least once. The ambient/texture sounds were really well placed; the track was well-produced over all, as well. The only other issue I had was the breakdown lost energy in the middle; perhaps you could shorten it, or have a bit more going on in it or something.
It's hard to say without the original, but it sounds like you changed the EQ or something on the drum sample... maybe tweaked the bass too or something? Again, I can't be sure... I do agree that it seems to fit in better. Around 2:40 I can hear the drum break clearly playing. I'm not sure if you added that, or just made it easier to hear?
The only change is the drum loop after 2.30, I like it better this way.
Hope I'll get some better tunes in the near future, stay locked and thx for the help
