For buildups, throughout the map does not increase in difficulty as the volume does in the song. The map only follows suit only when the rhythm changes as well.
For drops, they are underwhelming. They feel very similar to play to the rest of the map, just a bit more rhythmically complex. I please suggest using slider velocity changes for larger portions of the map as it changes. i could also recommend using different patterns or spacing during different sections of the song to create a "sense of change", you could also use the songs pitch to guide you.
00:31:603 - 00:42:853 : Previously, the map follows the kicks and vocal chops but stops following kicks here. I would convert it(the objects over the kick) into a triple, with last object being a 1/4 beat slider and a circle 1/4 after that.
01:01:602 (2,3,4,5,6,1,2,1,1,2) - The way these doubles are mapped vary widely and can be hard to read as the pattern change is abrupt compared to the rest of the map.
01:03:888 melody is on an 1/8 beat and there is a missed beat right after it
02:48:126 slider glosses over melody here
02:59:259 (4,5,6,7) - I would replace these circles with 1/4 beat sliders to follow that "reversed sound" on the blue ticks. Like what you did at 03:21:525 (4,5,6,7,8,9)
03:28:322 No sound here
03:29:493 missed beat
03:37:697 No sound here
Note: Upbeat song! Thanks for the opportunity to play and mod your map, and for sharing it of course. Good Luck!
