Really great composition! I enjoyed it all.
The background instrument that starts at around 0:29 and that ends at 00:56 might lack a small bit of reverb. More precisely, I think it would make the whole section emotionally deeper if you let the reverb last a little longer on each note. Next, at 02:34, the pace of change in the volume of the main instrument might be a bit too abrupt.
While maybe from 00:00 to 01:52 the mood doesn't change enough to me, as a whole, I think it's pretty much complete. I'm allowing myself to point at some stuff that could have been adjusted better *in my opinion*, but in the end this was interesting.
Keep it up dude :)
