0:00 Nice melody
0:10 I think the strings are a bit harsh. You might need to find a deeper, richer sound.
0:28 The voices here are kind of harsh and create a dissonance as if they're not supposed to fit together.
0:44 A bit too busy here, with the arpeggios and such all happening at once.
1:01 Also your snare pattern is a bit subversive, the snare is very unnoticeable but not in a good way.
1:34 I wish this would progress into something different. I think part of it is that that string sound gets grating after a while.
2:16 Needs a little bit more of a progression in my opinion. Some of the sounds sound a little bit out of tune, too.
I'm trying not to be too harsh, but this song is a little repetitious. I, personally, would advise against using this as a trailer song, until you've mixed this with nicer sounding sounds. I could see this being a lot better if you chose more rich sounds, more layered sounds, instead of ones with a very short attack and short release, which makes it sound tacky and rather repetitive and annoying. I can tell this track has some potential, but I think it needs special attention before that potential becomes more fully realized.
