Why hello there.
Drum 'n Bass and breakbeat are possibly my favorite genres, and I can see you will be soon a prominent dnb artist soon if you keep this up.
I've only got two pieces of advice for you: the reece should really sound like a reece. Take out a lot of the bass from the drums so the deepest they go is around the 200 Hz mark, and then make it so the bass actually has bass. Add a sub bass in the background or something to provide that "bowwwwwwwww", you know?
And second, don't use the Amen break as your main drums. Since it's a loop, it's impossible to EQ the snare, bassdrum, and hats separately. It wouldn't hurt if you sapped all the bass out of it and then used your own samples for your hats, snares, and bass drums, but using only the amen break for your main drums is a pretty bad idea.
Awesome work though; fix these things up and you'll have one hell of a library of drum and bass tracks to filter through :)
Could you check out my first track on this account? I've been working on it for a while and I got my friend Speedmetalmessiah to do a sick guitar solo at the end for me. If you could check it out and tell me what you thought, we'd both really appreciate it :)
Keep it easy buddy.
