Decent
I have to agree with the reviewer below although you fail to accept any criticism only praise.
You have a good bassline in there, but it feels like that might be it. It completely suffocates the rest of the track that you haven't spared any effort for, because you have just focused on the bass.
This could really be coming on to pro standard if you brought the drums up to the standard of the bass and sort out the little decorations you can almost hear over the top. I don't think you over used the crash, but you can have more than one crash in there which would sound awesome.
And what was meant by the lack of mixing is the fact that the bassline takes up what seems like 40hz-5kz with no space for the kick to breathe let alone the snare. Pick up an EQ and phatten up the kick and snare, and tame that dirty bass so that it fits in with the track. Not sure if this counts as promotion of outside sites but if you google audiotuts they have some good tutorials for mixing.
Oh yeah and wobble basslines are over rated. Especially in dnb. I don't say this because I'm closed minded, but because they are done to death.
If you don't like what I have to say feel free to message me on it, I hope I'm not being too hostile.
