I liked it.
As you say in your description, it does start slowly, build ups are no bad thing tho and i like the spacious feel and nice textures and layers u have created. I think the second part of the trk is nice and well structured and has a hint of chilled squarepusher to it, but the 'real' drums are not high enough in the mix to make it feel like there has been a significant development in the dynamics. Just get those drums up in the mix and you're onto a winner i reckon. A few extra little fx and glitches here and there wouldn't go amiss either. This is at 2.25/5 as I review it and in no way does it deserve that, so i give it 5/5.
