Drum n Bass!
This is some nice stuff. I'll start out with the drums.
Kick: wasn't loud or powerful enough.
Snare: really gritty. Just give it a little boost around 200Hz to thicken up the sound.
Hi-Perc: Good work! You hit the right middle-frequencies.
Amen: take it out. All it does is add extra noise to the background and muddies everything up. You don't HAVE to use it in every DnB song you make, you know.
Bass: The first sample needs work. the automation sounds nice, but the pitches are off in some little parts. Edit it some more tighten it up.
The second sample is really clean, though. EQ some higher frequencies into it, though. Maybe even throw on a distortion.
Work on the bassline some more. Make it more interesting and less predictable.
Pads: they sound nice, but are a little too loud. In a good drum n bass song, you should be able to keep the song running smoothly with nothing but the drums, bass, and some well-placed FX samples.
I give you 4/5 because it's one of the first real drum n bass song I've seen on the chart today.
