Thanks for the review, man! Always good to get a nice, lengthy critique every now and then! I guess I'll take some time to try and address some of the things you mentioned since you took the time to point 'em out :)
The pattern I used for the drums isn't actually that uncommon to hear in a Drum and Bass track. However, if you think it sounds weird, that's totally fair - it has that sort of "off beat" feel to it - which, personally, I love :3 You also mentioned that at 1:45 there are only "two instruments", which I can honestly say is not right at all... Haha, there are numerous layers of basses, sub basses, kicks, snares and cymbals playing. Just because it doesn't complex doesn't mean it isn't. You did even say yourself, "lack of instruments can be a good thing" - so I guess you get what I'm saying ;)
Those are really the only thing I wanted to address. I don't agree with everything, but for the most part, I do! And that's fine, it's impossible to get good reviews all the time! Reviews like yours keep me on my toes... Haha!
Thanks again for the review, man - always appreciated!
