Lot of potential
I like your contrast when you introduced the (sawtooth?) melody and then reintroduced the semiquavers and used other background instruments and lines.
I also like your use of sound distortion effects; you put them in the right places and didn't overuse them.
The loop itself gives off a good, happy vibe. I think that it could be more, though. The thing I think is holding it back is the octave bass you introduce at the beginning and which stays through the piece. To me, it's just too much; it's far too overpowering, and I don't think it really fits in well with the piece. Maybe if you got rid of it or greatly diminished it, and made the piece a bit more upbeat, the piece could have a far more enhanced effect.
Also, the strings near the end of the loop (those are strings, right?) create a dissonance that doesn't fit well with the rest of the piece; you made them play up to the leading tone, which was played quickly and did not resolve to the tonic. I don't think that fits in well with the piece; if it were me, I would have made them either resolve, or not have them go far enough to reach that measure that has them on the leading tone.
Just my thoughts, anyway. I liked the piece overall; I'm just saying the other things in case you wanted any input.
