2:40 has this build up before and it said drop the beat but it didn't really contrast any other parts of the song. I kind of expected that part to be a bit more different. I think you should have made the whisper a bit lower to help set the mood of the song a bit better. The main thing that changes in the song are the voices so I think the song could have benefited from being a bit more dynamic. Now it has a nice beat to it and it gives a chill kind of operation vibe to it so that's nice. Like a stake out scene in a movie.
Overall the only thing I have to say is that I think it needs to be a bit more dynamic. Besides that I don't think it's bad and I think it's really chill and vibey.
