How the fuck is this professional DnB?
You shouldn't go around calling yourself a professional since you clearly know nothing about the real world of professional Dnb that reaches past Pendulum.
I mean, how hard is it to understand? Drum... the drums in this are OK. The kick is weak and the snare needs more low-mid frequencies at 200-250Hz. Bass... here the bass is nothing but a simple, mildly distorted and phased sawtooth. It needs more low end, distortion, and should ALWAYS be mono.
Concentrate on the Drum n Bass more. They should always be the main instruments in drum n bass. If you don't like that, then just call it something else. But trance arpeggios and crowd cheers just don't belong in Drum n Bass.
Go to Wikipedia's drum n bass page, you might learn something. Also stop by LiftedMusic.co.uk to get some inspiration.
I'm not saying there's much wrong with your music. I can tell a lot of effort and talent has gone into it. But you just can't go around calling this stuff "Professional DnB", because it's light years away from it.
