Very nice ambient at the start. After around 30 seconds, I feel like you should put less reverb, also with it being a tad repetitive. After around 1:10, it's decent, with a transition to the next part what I feel is fitting for a song like this. After 2:10, we have a nice break from the drums to see more ambience, but again there's a tad too much reverb with the noise. At 3:00, we get to hear a completely new instrument added in the song, which is a nice change, but the acid shortly after isn't that fitting for this song, maybe another layer of lead. 3:47-4:20 is almost the same as 0:30-1:10, might need a bit of variation. I would say the worst part is 4:20-4:36 since almost everything drowns out with each other.
Overall, 6/10. You should fix the repetitiveness of the song, much less reverb and that last part, which again drowns out almost everything.
