Good, but a little repetitive
I think that this is a nice sounding piece all told. The major issue that I have is that the only real variation you added was the outro, which really sucks for a 5 minute track. This kind of sound got quite old quite quickly.
For some improvements, I'd consider changing the piece so that the intro doesn't take so long to build up and get us into the track, because that's almost a minute that you could halve, because the increases in volume were so minute, the casual listener would think that they were never going to get there.
You've added backing pieces to the music, but the way that it pans out, it's as if there is something trying and failing to make itself known to the track. With the piece being dominated by the rhythm, you need to crank up the volume on the melodic parts, if you want them to have an impact, which this piece sadly lacked.
