Dayumm I love the sort of grimey bass you got in this one. Breakdown in the middle is chillded out and has a nice bridge with the following part. The pads you hear in the background hold the whole thing together.
One thing though: I know this is drum and bass, and your style can be quite chilled out and continuous, but I'd really love to see part of the second drop with something that makes it stand out more as a drop. This aside, pretty much flawless.
Really great song, keep it up!
