Okay, here's my 2p for this piece:
1) Your chords are alright, I smiled at some of them. :D They were good!
2) Some of the synths are overpowering, and one of them is off-beat.
3) The percussions in this piece are quite alright too. : )
4) The ending was abrupt.
Now with trance, your goal is to make people get lost in the music. I didn't get that wow factor, and that's what makes me dock a few points out of this piece. Good trance pieces have that factor in them, and they also make use of dynamic changes at some points in time to build tension. I do not know if I can say much about the dynamic levels, but hey. Knock out the kinks, work on what makes this piece special, and you'll be on your way.
