The "ding" at the beginning was a good idea, and I like the automation at :04 too. The two riffs playing at :06 kinda clash with each other, and in general the sound design is pretty stale and lacks variety. The return of the "ding" at :54 wasn't anticipated very well. The main pads you use at 1:06 (and throughout) sound pretty muddy in the lower frequency range, yet at the same time the texture is both minimal and dry for most of the piece. Some reverb might help, but I think the main problem is that you need instruments that blend well together and sit better in the mix. The transition at 2:12 was good, although by that point the overarching structure is beginning to feel quite repetitive (i.e., ding, then automated fade-in, then the introduction of another new riff). I also thought 2:40 sounded straight-up dissonant harmonically, and I'm not sure that's what you were going for. You have a lot of different riffs and patterns sprinkled throughout this piece, and tbh it's not immediately clear to me how they're related harmonically. I'd suggest consolidating some of these riffs and fleshing out the ones you think are the best. Right now, you have a boatload of ideas bridged by the "ding" transitions, and I think it's a bit overwhelming from a structural standpoint, despite the minimalism in the texture for most of this piece. I've been really tough on you in this review, but I think my criticisms have two main points: 1) the instrumentation doesn't really accomplish much. It's a generic, gritty-sounding synth that doesn't really help channel the mood or anything. You might want to experiment with simply using more instruments in your piece with the same notes before anything else. AND 2) The structure doesn't feel very cohesive. You've tried to take the piece in a lot of different directions, and all your ideas are simply separated by dings. The piece would be more effective if you had some more repetition and phrasing instead of sudden changes. Don't get me wrong: the piece isn't all bad. I like the ominous descending line at 2:01 and the low percussion that's in the background for much of the piece (e.x., 1:04). Hope this review helped you! Keep at it, man.
