The beginning (0:00-0:45) of the song is pretty much the same thing over and over, just like the rest of the song.
It didn't really have any climax, it's just the typical Boten Anna beat over and over with some vocals.
I don't like 3:40, after the Are you ready? sound the song should get more intense, but it keeps the same beat and the same tempo.
If you're making a v3, try making it less repetitive and put in some points where the song gets more intense.
