Woooooow.
2:00-2:50 was just wow. This track is HUGE. A repeating lead synth is a good thing when one can blend a good sound around it, and you've done that this piece.

It Reminds me a bit of Tiestos, "In search of sunrise" Asia Vol.7 album, and how he does the same thing. Repeating lead synth, but what he does, is what he cuts the lead, and keeps what he's built around it going, then flows it into a whole new track.

ANYWAY!
On an ending note, you've got a talent. but this is more of a video game track then something I'd want to listen to when just playing some CS, or at a party. That said, it was still enjoyable.
Keep at it, hope to hear more!
