Nice, solid Trance...
I like it. You've got a very nice revolving beat to keep things going, and the instruments are pretty darn synth-tastic! I've listened to this a couple times through, and I find it pleasing to my ear-holes. The first time through I wasn't sure if I liked the way it came in, but I have to admit that it's grown on me. You could probably make a nice loop out of it if you could connect the front and back ends, but loops can be a pain, so....yeah.
It does seem a little too repetitive, but I can appreciate the fact that that's more or less the nature of Trance. There are some cool instances where you experimented by adding something different, but those were pretty few and far between. I would have liked to hear some more key changes since there only seem to be a couple.
My suggestion is to experiment more with harmonies, and I think the bass lines could have a bit more variation, as well. When the music becomes particularly sparse around the 2:50 mark something in the timing of the bass sounds a little off-tempo, but it's difficult to tell for certain. The length is impressive at just over five and a half minutes, too. Good on ya!
