Lovely tune mate, keep them tunes coming!
I agree with FelixArk down there...the track is heading in a good direction, but the harsh noises just don't fit with the chillness of the track at all...the melody is fine, but maybe tune those down?
(Yeah, I can see WIP...these are called suggestions and constructive criticism. :P )
As far as Dubstep music goes, you have a lot of the key essentials in place. Decent setup, great drop. I think it's around 1:40 or 1:45, when your sounds get really sharp is where I kind of get turned off. Were not for those harsher noises, this would be perfect.
It sounds like a robot monkey.
Please contact me if you would like to use this in a project. We can discuss the details.
