Interesting polyrhythms going on here. Some comments on mix and structure.
Reverb here is 100% out of control -- tame that low end by throwing low cut up to 250 hz so the instruments aren't all muddying together. Gated reverb will sound better for your snare, btw, than that long tail. Hell, use it on everything if you want. It's a lot cleaner than just point blank reverb. But if you must use reverb, try to cut it down.
Now, I am a big fan of all your elements -- although they all sound panned left. That could be because your drums are mostly all on the left.
Protip, there are a ton of 808 and 909 sets out there that are free. I think 99sounds has one that I regularly use, for instance on my latest track here on NG, Progressing Degrees of Insanity, if you want to hear what I'm talking about.
Unexpected sections here and there, but this piece is already adventurous enough that I just get used to them.
Your drums I will say, are almost totally buried in reverb and just from not being loud enough in the mix. I would turn everything else down. And probably recommend centering that lowpass bass synth.
I don't know what the noise was at 4:35.
Are you by any chance using Trompette paper trumpet synth? I swear I recognize that flappy noise.
Thanks for coming out to NGUAC! Really interesting listen :)
