General suggestion: BPM should be halved (BPM: 78) because this song is mainly in slow tempo, even there's powerful part of the song

https://osu.ppy.sh/s/42342Check the BPM for both
I'll post my mod once u finish the map
EDIT: if you insist stay at 156, no much problem. BUT it will tell the players that this song is fast-tempo song
01:14:804 (4) -
remove this note*, because the gap between this circle with other objects is disturbing in this section (
1/8 beat for BPM 156, OR
1/4 beat for BPM 78), and i'm sure the objects gaps before and after this section is pretty constant (1/2 ~ 1/4 beat for BPM 156, OR 1/1 ~ 1/2 beat for BPM 78) unless if you're trying to make an insane map
EDIT 2**: 01:14:804 (4) - This note can be also keeped IF:
1). The BPM is 78 , AND
2). You make the section from beginning up to before this 01:14:707 (3,4,1) to be harder (use 1/4 beats in BPM 78 more oftenly)
If you not make what i tell above, this 01:14:804 (4) will be more likely skipped by any players
This will make the player more prepared for this more difficult section
** i just realized you're trying to make an insane approved map
*Considering from what you've done until to this section
1/8 beat is rarely used in any osu! maps (if not never used)
Further mod coming soon!
