Nice work!!!
Awesome song, not too crazy, but upbeat for trance.
I like your buildup a lot, simple, but it sounded great.
The whole thing had a very driving beat, it came mostly from the background synth, it held everything together well and I really like the sound of it.
I would have liked to see another synth or two in there to switch it up.
This could easily be extended to a six minute song with an interlude or another chord movement :P not that 4 mins is bad for a song, much better than many I've see here, and also not too short, it just could have been that much more awesome if you would have done something more.
Overall great work, pretty chill and still something you could jog or work out to!
If ya don't mind check out my stuff, I'm just starting out with composition, let me know what you think and maybe when I get the full FL studios (not just the demo) we could collab on some crazy awesome music? Lemme know.
Anyway great job,
