Some custom combo colors would be nice imo
here are some based on the background, I used the Automatic Combo Colour Picker in Digital Client
[Colours]
Combo1 : 249,174,101
Combo2 : 128,108,68
Combo3 : 240,93,73
Combo4 : 246,164,143
Combo5 : 174,161,187
04:00:349 (4,5) - these two are unsnapped slightly, this is true on all difficulties
Normal:
03:58:563 (1) - This sliderbody has additions. You may want to change this to only have hitsounds on the tail and head instead of the entire slider.
Hard:
02:10:766 (1,2,3) - imo something like this would sound better

03:21:444 (1,2,3,4,5) - this is a pretty big difference to rhythm density treatment compared to earlier in the map. earlier in the map it felt like you were trying to avoid triples and bursts, but then all of a sudden we start getting some halfway into the map. Like if this can be a triple 03:36:952 (2,3,4) - shouldn't stuff like this also be one? 00:30:596 (5). Maybe you were trying to create more emphasis around 3 minutes with the triple but idk I feel like the intensity is similar.
01:42:291 (1) - This sliderbody has additions.
03:58:563 (1) - This sliderbody has additions.
Top Diff:
01:02:630 (10,11,12,1) - the density here is lower than on your hard difficulty at 01:02:630 (3,4,5,1). Make sure your higher difficulty always has higher or matching activity in terms of tapping. Maybe the way this is mapped should be flipped in the two difficulties?
01:37:080 (5) - This sliderbody has additions.
01:42:291 (1) - This sliderbody has additions.
03:58:563 (1) - This sliderbody has additions.
04:00:596 (1) - This sliderbody has additions.
Nice map.
