change the sliders a bit, and then you're cooking

Add notification sounds throughout the song

BG is too high resolution

00:52:885 - change these to 1/8 sliders

There's many notes on ticks with no sound example 00:09:094 00:41:695

Spacing consistency and emphasis doesn't make sense. For example at 00:06:670-00:07:295 the spacing is even but at 00:07:920 the spacing shortens with a increase in slider velocity making which is bad because it poorly reflects the music because there is shorter spacing with more important sounds. I would fix this by increasing the distance between 00:07:295 (6,1) -

In general you should pay more attention to spacing and sounds to better reflect the song

Timing is off change offset to 2,948 and resnap objects.

The slider velocity increases and decreases too drastically for a normal. This creates a difficulty spike for new players which could be hard for them to follow.

For example at 00:05:420 the slider velocity is lowered even though there is no change in song and then at 00:07:920 when it is raised back up by .5 which is higher than the maps starting velocity. I would fix this by sticking to smaller velocity changes and only changing it when necessary to the song.

At the start of the kiai 01:07:920 you lowered the velocity which adds a underwhelming emphasis to the song so I would suggest having the kiai slider velocity higher than the rest of the map. Since the kiai slider velocity is already at 1.05 I would lower the rest of the maps slider velocity

Hey the custom skin isn't necessary since it's just a old version of the osu skin

New to modding so everything might not be 100% correct but I would say most of this is valid

Ok so first off I'm not sure if your current style is 2013 mapping or if you just haven't updated the diff so I'm just gonna give some pointers on some stuff

First off just I would recommend working on the basics like rhythm, flow, and linear motion.
A bit of your sliders start on a high hat and end on a snare hit, which makes the emphasis/rhythm of the slider bad

00:03:422 here you place a note down which doesn't follow up with anything so I would suggest just either moving that over to 00:03:596 or making the 5 and 6 note a slider either one works

In some parts you choose to follow the vocals which create for weird rhythm choices. For example here at 00:05:515 this slider messes up the flow of the drums. Other Examples 00:16:678, 00:21:561, 00:36:387 ?

There's a lot of sections where you just don't map anything at all 00:25:573, 00:29:061, 00:31:503, 00:44:061-00:45:457, 01:11:619-01:13:712

Weird spinner 00:48:945

I would just try remapping it and improving the rhythm of the map following mostly the drums.
