Disclaimer: I know very little about Trance or any EDM type music, so I'll try to avoid critiquing any genre specific parts of this.
Overall the song is solid, however, I feel like the transitions could use work.
You have the intro, which on its own is perfectly fine, however when you go into the next part at :33, it feels fractured and very sudden. This may be because you are eliminating piano-y thing, plus the percussion, as well as the bass while simultaneously changing the synth of the melody(?). That's a lot of change for a listeners ears to take in all at once. I almost feel like you could practically switch the two parts with some minor adjustment and it would help the fluidity of the song.
Everything from :33 to 2:30 is fine, although I feel like there could be variation once the piano-y thing is introduced at about 1:30. Maybe a small change to the bass or a subtle addition to keep things interesting? But overall this part is very smooth and enjoyable.
The change at 2:30 felt SO anticlimactic. You have this break at 2:01 that then builds us up for 30 seconds and then......You go the outro.........
You could have easily made this song another 30+ seconds longer by just returning back to what you had at 1:30 and maybe even keeping some of the piano work from break going to smoothen out the transition and THEN proceed to the outro. Not only would it make the song longer, but feel a lot more satisfying to the listener.
Criticism aside, this is still a good and enjoyable song. The synth choice is good, mix is decent, and it definitely has some good ideas going.
