Any time you use those kinds of classic trance synths, try not to leave them dry, you should always dress them up a bit even if it's just with a touch of reverb.
Cool trance track, well layered, good choice of instruments. The structure is really good, and you also did a good job on the mixing.
Around 2:10-2:15 you have a really catchy thingy going on there, I prefer it over the atonal mood you seem to be going for with he main piano instrument, I think that's what the last reviewer was referencing. It's not really a piano, or maybe it is, a bell or piano, whatever it is you know the pattern that we're talking about.
It's being out of tune doesn't go with the rest of the track, because the rest of the track is a solid trance song for the most part that is all in harmony. Around 3:40 you add some odd elements as you do here and there throughout the song, but not enough to warrant it.
I think the main issue with this track is it's trying to be two genre's at once, solid trance, and a more experimental techno kind of track.
But, it's still pretty good. I feel your mixing is pretty good, and your writing is pretty good too. So, keep up man. But I wouldn't definitely take note of the reviews for this track and work what you learn from it into your projects.
I want to give you a four because I really like the trance elements but I can't. The being two songs at once isn't working, I think you could strip away the atonal bits and make this a pure trance, and then maybe save the more experimental patterns and make another song out of them entirely, you could make two songs out of this.
