I definitely would take some reverb off of the kick - it doesn't need it and almost takes away from the rest of the mix. I really like the vocal work at the beginning though, the sample are cool and used well.

I like the melody of the synth that comes in at 0:30, but I don't love the timbre of the sound. I think it's a little too natural sounding, and isn't quite processed enough. I like the trance-y lead that comes in behind however starting at 0:45 though - it has good energy and has good presence in the mix.

I like the buildup starting at 1:19, but I think if you would add some white noise to it it would really make it shine. I would also cut the vocal samples at 1:31, I think that section would sound harder without them.

The mix actually isn't too bad so far, even before mastering, nice work on that! Not too bad of a vibe in this track either!
