I don't know if nostalgia is what you're going for, but I think it's a great thing and I have listened a few times because of it. The lyrics work well with your voice and the effect you used ^_^ Thank you for making this.

I'm hearing a lot of good stuff in here. The intro has a nice buildup and I like the synths you use. Of course, it would be really cool to hear more mid-tones (filler sounds if you think it works) to counteract the emptiness between the drums and the synths. I would also say the same for the second part with the beats. It helps (for me) to focus on the important beats and emphasize them with chords or a good arp. In the third part with the key/beat change, I'm not sure what you're going for, but if you wanted to go for a sort of breaking-down, uncanny feeling, it might be more impactful with some sort of bass tone as well as a stronger transition into that part - (especially since you seem to be doing a beat drop from the previous part. But honestly, I like that you have definitive parts to the song, it makes it dynamic. I guess just work on transitions in general :) Pretty cool
