00:06:525 (4,5) - This is a bit overspaced if you compare it to 00:06:206 (3,4) - . Also this slider could follow the 1/3 rythm https://gyazo.com/4dfaf90e2094db7e65a13cb404d8aee8 like this.
00:13:546 (1,2,3,4,1) - This pattern is correct, but the problem is the spacing you give between this two objects 00:13:866 (4,1) - so it's considerable to be a 4 stars diff.
00:31:419 (2,1,2) - This rythm would be better if you ctrl+g these 00:31:738 (1,2) - so it would give more impact to the vocals and it would fit so much better.
01:22:057 (1) - Happens the same with this
Sorry ignore this second one, it flows well with the shape.
This 00:48:121 (1,2,3) - is too much spaced from 00:47:589 (4) - since you are using a triple just a 1/4 gap away from the slider and it looks like a 1/2 gap so consider to approach the triple to the slider cause it can cause missread. Somethhing like this would be fine I think https://gyazo.com/a44bae7d4b80011d6f2c83064a077233
I'm not really good at slidershapes, but this 01:08:440 (1) - with the slider velocity it has makes so hard to don't break combo because of the shape it has.
01:13:121 (3) - I recommend you to use a slider here too like you did with this 01:12:270 (1) - or this 01:12:695 (2) - since it's the same sound and it will give a really good flow. You can easily connect it with this one 01:13:546 (1) - if you change it :D
01:27:057 (3,4,5,6,7,1) - I know I've already mentioned the problem of spacing here, but apart of that the flow feels a bit weird, I would do something like this https://gyazo.com/353459e0d77d0f7157482eca3b457641
