Cute song!
[Best friend]
00:45:194 (1,2,3,4,5,6,7,8) - Considering to adjusting this into a more apparent 2+2+2+2 or 2+2+4 patterns as per the vocals.
01:09:569 (1) - It is recommended to take this apart because 01:10:037 is strong enough for a slider head too!
01:30:428 (2) - Pretty overmapped. 03:00:428 (2) - Same
01:31:365 (5,1) - Considering an overlap like 01:32:772 (3,4) - .
01:43:787 (3,4) - Such a large spacing plays weird and abrupt amongst a series of spacings like 01:43:084 (5,1) -
01:49:881 (4,5,6,7) - Why suddenly four such sliders? It bursts the rhythm intensity without suitable reasons imo.
03:08:631 (1,2,3) - I would sincerely request to keep the spacings consistent across 03:08:631 (1,2,3) - and 03:09:569 (4,5,6,7) - .
03:30:506 (4) - This might cause potential readability issues for the current layout looks pretty like two circles.
03:31:131 (1,2) - These are not snapped. Also the stack of 03:31:014 (7,1) - prevents player from reading the reverse arrow clearly, which is definitely not allowed as per current ranking criteria.
03:40:037 (1) - 1/1 downbeats start to appear on this section so better map them out too.
03:50:819 (1,2,3,4,1,2,3,4,1,1,1,1,1,1,1,1,2) - Unnecessary and irrational difficulty spikes here. Strongly recommend to nerf them.
04:47:186 (2) - Not snapped. I'd like to recommend overlooking it just like 04:50:819 (1) - .
04:52:225 (4,5) - Place 4 in the middle? Better aesthetics.

Your current draining time is 4:59:532, which is not rankable. And you have already overdone the spinner extention. The actual draning time of this song is even shorter.
