It's a little too empty and sporadic for my liking. It's also clipping at the end when the delay is running over itself.
If you're talking about the very last sound you hear, it's actually vocals that have been extremely comb-filtered and clipped on purpose to make them sound that way.
Interesting piece, it gives the feeling of peace! Sounds really smooth and good to everyone's ears, Also the part at 2:57 is amazing, nice work, nothing more to say you know what you do better than I do
Wow, thanks! Glad you liked it!
