I really like the introduction; instead of gradually introducing and creating themes, you fade the listener into a preexisting musical world. There is a pleasant, airy ambiance that has a strong presence yet is difficult to discern; it makes me visualize a sky world. The slightly distorted flute does a nice job at foreshadowing the trap nature of the track.
The bass sounds very crisp, and the drums sound light and clean, which further establishes the sky world visual for me. And the drum rolls are well-done and very pleasing!
The melodies themselves aren’t that interesting, but the pitch bends and automations vitalize them, and the choir pad creates a nice harmony. The piano also enriches the atmosphere and adds passivity to the track.
I have no problems with the mix.
I like the ending, but I think I would have kept more elements toward the very end. I understand why you chose to keep the static reverb atmosphere, but why did you fade out almost everything else? To me, it unnecessarily contradicts the lighthearted introduction.
This is a fantastic track! :)
