I like the atmosphere at the beginning and the blissful vibe of the initial melody. The pause at :14 was a bit awkward; I would’ve at least let the reverb bridge the gap there. That said, I’m enjoying the melodic content at :15, even if the drum samples are pretty generic. The drop is pretty cool, and I really like the melodic content at 1:15. I can hear the drums struggling to cut through the mix, though. Some stricter equalization and compression might be in order. It might even be more of a volume issue than a mastering issue, really. The atmospheric part at 1:48 is really nice, and I like how you left a lot of room for contrast with the second drop. The variations at the second drop were nice, and I found the rhythmic content consistently engaging. The piano outro was a nice touch, too. Overall, nice work with the production, drops, melodic content, and atmosphere. I have some minor issues with the progression, mixing, and originality (especially of the arrangement), but this piece is solid work in my book. Keep at it, Plygon! :)
