After sticking with what I already knew in electronic music for a while, I finally caved and listened to this on YouTube to see why I was getting recommended it so much. I like it! It's fast and layered without being overwhelming, and has well-written lines that take turns being the focus of the piece, giving it variety throughout. You also nailed giving it the type of flavor you described in the description - sci-fi, emotionally stirring in parts, and sounding like a story belongs with it.
My only nitpick on this is that cello instrument in the beginning, and potentially the other two instruments meant to represent non-electronic things (choir and piano), sounds very clipped and obviously synthesized, like a bad MIDI or retro video game instrument. Perhaps you prefer that sound, but I like more realistic string sounds better. With the other two, the synthesized samples do sound decent and have a sound that works with the rest of the piece, but the MIDI cello just made me expect more bad samples throughout the piece.
Overall, though, this is some pretty good electronic composition right here! I enjoyed listening to this!
