Really nice, I like how you've got this going. The snare could use a bit of modification, but that's nothing too bad. What I think could improve the meditative vibe of this song a bit is varying the velocity of the lead instrument a bit more (the one that comes in at 00:27) to give it a more human feel. Also, this is personal preference, but I'd take a bit of the brightness of it away. A darker tone would REALLY add to the beautiful pads in the background. They give off a really ethereal, distant vibe, while the lead sounds very close and bright, almost like it's about to switch genres (in a way, it sort of does, I suppose). Lastly, I'd suggest keeping some warmth/dark texture in the background during the dubstep section. Not as overt as it is in the rest of the song, but something subtle to continue the idea of a relaxed atmosphere.
Very nice work so far, I'm quite enamored with the sound of this! =D
