Not too much for me to really comment on, rhythm looks pretty solid and the map has some good ideas.
The only thing I would note is probably clean up some of the sliders and make sure that the angles between the circles are consistent, since the majority of the sliders follow a smooth curve. (For example: https://gyazo.com/f68872920600a53e9a2d6efa217270ad 00:35:130 (3,4,5,6,1))
I'd also probably look into making sure that similar patterns have the same slider curves as well, for example 00:45:049 (2,3,4) & 00:45:538 (2,3,4) have differing slider curves compared to the same pattern prior at 00:29:376 (2,3,4) & 00:29:865 (2,3,4)
02:48:258 - In order to represent the intense vocals here, consider increasing the spacing between the sliders a lot (to differentiate it from other parts of the map)

Makes you need to snap aim which is a good change of pace.
02:32:450 (4) - New Combo such that players won't confuse this for the pattern around 2157970#4268701
01:56:104 (4,5,6,7) - Reduce spacing slightly to match with 01:55:411 (3,4,1,2). Also make sure the spacing between 4-5 6-7 is the same as 3-4 1-2
01:33:373 (1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8,9) - Spacing here is vastly larger than 01:37:411 (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15)
I'd recommend starting the spacing smaller and building up to match the growing intensity of the song.
