I don't think it's fair......
That your reviews have been so harsh.
Yes, it could do with a bit more mastering, and the pluck could do with a bit more variation (repetitive is expected, but this just feels like it...you could just try playing with that for a bit) in places... especially on those last notes, just needs a shift down in octave at the end of the phrase and your laughin....i like it. Yes a full quality one would sound better.... but i think this is bloody good.
Level everything out a bit more and your onto something good here...
The main beat and build up is really quite good, get's you ready for what's coming up and when it does break it has the right feel to it..
My advice, put some more time in to the mastering of this, maybe balance out some of the samples, the small quiet section at around 2:30... needs something going on there... but when it comes back in at 3:40 it's immense!! steppin up again around 4:08 takes this song to the end on a massive high, plenty of time for a solid mix to be done if played live..
Like i say, i liked it, get a 4/9 from me.... keep it up... i want to hear a better version of this ya hear ;)
