Easy.
00:26:106 - Since the instrument ends here, the music of 00:24:392 (1,2) wasn't exactly the same. Expressing those difference as a same 2/1 slider didn't felt to be reflecting the song properly imo. Mind just using a reverse slider at (1) which ends at 00:26:106?
Normal.
00:40:677 - The drum beat here is pretty strong. Keeping it inside the slide didn't really felt to be reflecting the music nicely.
Hard.
Please use slider tick 2 because the song is mostly having beats every 1/2. 00:28:892 - 00:30:392 - etc. Keeping these existing beat in the song with no expression at all didn't felt to be fitting. Tick 2 can solve it.
00:20:963 (1,2) - Just fyi in your future mappings, such penetrating slider concepts aren't really effective when the base spacing is higher than 1.00x because as you can see, an overlap happens between the path of (1) and the end of (2). Just keep this in mind for your future works.
Insane.
Same opinion for using tick 2.
00:43:677 (1) - Even I can hear that a sound exists here, I'm not really sure if this is really necessary to express. It quite lower's the emphasis of the previous drum-jumping sections imo but more importantly, the setting made the ending spot inconsistent with other diffs. It didn't really felt nice to happen in such a set.
If you could care more about structures and consistency over the music sections more than individual flows only, guess you could show some better quality work at the future. Not a bad work overall.
Yet I'm not really interested in nominating this set, so,, I wish you good luck.
