-for trance songs, it has gotten to the point where all the synth rythms are played out, as well as the pulsing bassline. Now it is just a matter of picking 4 or more chords to cycle through that don't sound annoying. 'Hooks not required'
-the part I like (somewhat unique) about this track is the slide, except that it is only used in the break/build. I think you should expand on it, and turn it into part of the overall melody, rather than the just the chord cycle(phrase?).
-the high synth sounds like every other trance song from mp3.com. Unless you are going for that, so that you can label your song "trance" I would suggest using a different waveform (synth sound, not sure if I have the terms right), or maybe using the same pattern (melody) and cycling through waveforms. Damn, I just gave myself a good idea. . . .later.
