This shows potential.
OK, I'll be blunt here: This did not go over well as a quality production. However, I can say that from my own early days as a producer, you seem to know what you want to get out of your production and lack the experience to get there, and for that, I applaud you.
The rolling bassline showed promise to the idea that you understand quite well the concepts of Drum N Bass/Jungle as they stand today, it had a very techstep type feel to it. The break (the ever obligatory Amen) was appropriate but it was not hard hitting enough, uncompressed and unexciting. The lead synth was a bit over the top in terms of being part of the mix, drop the gain down a little. It was also a little frantic, and it sounded as though you where relying on it to give the song the extra "panic" it needed, if you will.
The overall mix could have had some chorus effects sprinkled in lightly to add a bit of dimension to it, and it could have used some compression and reverb as well, but these are all things you learn as you go, so I hope you don't take all this as trashing your tracks.
KEEP PRODUCING. You have an ear for this, and you can only get better from here!
