Drum & Bass First attempt

Hi there,

So I'm a total noob in production, I mean since a long time I'm making fun with Garageband but nothing to do with real production.
I tried Logic and as a dnb fan i came out with that first attempt.

First I was pretty happy of it, and then I went here and listend to some tracks you guys have been posting and I was like "Owww... I sound like shit" lol.

So here it is, please if u think its shit, say it but say why its shit and why should i try to improve and work on, thanks a lot, any advices is really appreciated.

Thanks you for your time.
