Very Nice!
This is brilliant for your first techno/tranceish piece!
I love the stereo effect you have going in the intro.
At like 1:12ish, I love how you bring it down, but I would looove to hear a really soft pad or something with the melody. I would probably use the one that starts at 1:23, and just keep it really quiet. (I'm really just throwing ideas out there) Just a personal preference; I like having that bass/chordal foundation there.
At 1:38, I like all the parts you have going. I would maayybee suggest turning down the pad with all the distortion/noise just a little bit, I feel like it covers up the other parts.
3:00ish. Love it. The only suggestion I could make is starting that section softer, and building up the volume until the 3:30 mark and putting some kind of climax point there because that part does get slightly repetitive and the volume change would make it more interesting.
3:56: See 1:38.
Overall, fantastic piece for your first one in the genre!
9/10, 5/5 from me for a few personal opinions here and there.
