Nice!
So, this is a good first submission, so I will assume that you have been making music for a bit.
The first thing I noticed was that there was a bit of static on the high frequencies, try filtering to remove.
The second thing I noticed, was that it was repetitive. It is pretty much the same theme with a few minor changes, for about 2 minutes. Now, if it was an eight minute trance song, that would be ok, but it is very short, so try either extending it or making it longer.
The third thing I noticed was that the background synth with a phaser on it should have been a bit more dry.
The kick was not strong enough, try adding a multiband and adding more bass, and then trying to eq it to as close to 0 as you can without going over.
Now, for the most important part - post production mastering. I noticed how the waveform did not seem compressed or soft-clipped, and that is good. However, I did notice that the master track was eqed, and that is OK, as it is minor.
Now, I liked the complex bass rhythm, but I would have preferred to see it sidechained to the kick, as that makes it duck when the kick plays.
I also like the reverb on the snare, it makes the atmosphere better.
Overall, I liked it, but there were a few details I would have filled in had I been making it.
