00:03:248 (1) - doesnt really look good when its almost parallel to the x/y axis maybe rotate it 5ish degree

00:08:248 (1,2) - could be facing downwards cause of the same reason that Krisom said to 00:23:319 (1,2) -

00:08:248 (1,2) - maybe doing the same slider to represent similar sounds?

00:18:248 (2) - could be rotated to the other direction cause at least imo it being parallel to the 00:17:248 (1) - isnt looking particulary nice

00:23:319 (1,2) - considering the pitch of the violin goes downwards, I'd suggest making both sliders face downwards as well for music representation

00:29:248 (1) - Could you make a pattern similar to 00:30:248 (1,2) - so you can follow the clear violin sound at 00:29:623 -

00:29:319 (1) - should end 00:29:694 - and 00:29:694 (2) - should be 00:29:819 -

00:31:248 (1,2) - These two objects seemed to be too close in this difficulty, it resembles 1/2 rhythm here

00:34:248 (1,2) - i don't think this spacing is nice, player might 100 on the slider or won't read the next circle well, it happens a few times

00:38:819 (2,3,4) - Since this is a triple stack and it's 1/2 spaced, I'd space/stack it differently to emphasize that it's not 1/4.

00:40:319 (1,2) - jump seems rather intense for such a tame part in the music and also considering most jumps in hard diffs are way smaller. I'd suggest placing (2) closer to (1)

00:42:248 (3,4) - this is even overlapping, making it harder to read.

00:43:748 (2,3) - at least from the expirience of watching my friedns playing osu, this might lead to some missreads and flustration cause they clicked 3 before 2 cause they thought it was just going in a straight line

00:45:248 (1,2) - The spacing is too confusing, I think you should separate them

00:48:248 (1,1,1) - maybe space it just a tad bit to get rid of the overlap

00:53:248 (1,2) - The jump looks too over even in the kiai part. Consider nerfing this

00:58:748 (2) - this is pretty high spacing for a 1/4 jump, would recomend reducing it to the same levels as for example 00:57:248 (1,2,3) -

01:01:623 (2,3) - spacing could be increesed to show the 3/4th gap

01:18:319 (1) - I'd consider either making this just a circle and stacking 01:18:819 (1) - under it, OR silencing the sliderend.

01:27:748 (2,3,1) - the overlap is pretty ugly imo, could be spaced more or less to get rid of it

01:31:319 (2) - Not gonna lie, this wave slider looks really awkward. i personally use mapping tools to make wave sliders because i'm so particular about how sliders look.

In addition, the blanket towards the nc looks a bit off.

01:43:748 (2) - could be moved somewhere to the right so that it does not overlap with 01:42:998 (5) -

01:50:623 (2,3) - the spacing could be increesed to show a 3/4th gap
