Somehow your CtB diff got through with only two really small mods from CtB players that I can see in this thread. While I know you are confident in your mapping, no map is perfect (where did I say that before?). You should have had at least one good CtB modder look at it before it was ranked. If other people did look at this set then it should have been mentioned somewhere.
There was a couple things that really stood out to me that I would like addressed. I'd appreciate it if you would properly look over them.
Rain
00:30:246 (3,4) - This could almost be called an edge dash, but there is no change in anything at all in the song. The lyrics are slowly decreasing and has no real change until the slider end, so you could potentially make the distance snaps smaller as they go on in this bar, but a sudden increase makes no sense. You could give it a similar angle to the last two sliders to fix this, or something else you could do. It's unplayable unless you've memorised it's there.
00:37:294 (2) - Same thing as above, while it's more justifiable because of the "drop", it's still too far to be have any flow.
Those two points above are the main reason why I feel it needs a DQ
00:39:463 (5) - Putting the circle on this side has some really weird flow, and there's no real change in the music to have antiflow like that. It's difficult to read because there's no way to predict it.
An example of that circle flow being used correctly was 01:17:076 (7) - While I didn't like the last one, this one is fine because you established the right left pattern with 01:16:172 (2) - just before.
00:40:728 (4,1) - This hyperdash is insanely far compared to everything prior to chorus. While the singer does go a little bit lower, it's nowhere near enough to make this reasonable.
00:59:704 (1) - There aren't any non-hyperdash jumps in the kiai sections that are close to being this far apart. Move it closer or make it a hyperdash.
01:14:342 (1) - If you're following the hitsound patterns of the other diff, then this needs to be soft. Sounds weird when half of the same bar is soft and half is not.
Not worth a DQ on its own, but I'll mention that 00:21:210 (2) - might be too far by a couple pixels. That and the Final spinner is missing the whistle that is used on Hard/Insane/Conspiracy
I would ask that another good CtB modder takes a look at this if it does get a DQ, since I know that the BN/QA team is better at this than I am.
