Although this is diff uses more space that Easy. Normal and Insane, i would say you can use more of the editor in some sections, for example:
00:14:415 (1,2,3,1,2,3,1,2,1,2,3,4,5,6,1,2,3,4,5,6,7,8,9,10) - Its basically 10% of the song mapped in the center, ignoring the lack of empashis (which #4731035 already covered but idk if you already changed or not), this feels boring to play and watch
You should really force yourself to use more of the space in the editor, ignoring then is a huge loss of opportunity of visuals/paterns that you could use.
From what I see mostly there are many problems with emphasis and intensity, there are strong sounds like 00:03:594 (2,4,1,3) - , 00:05:931 (3,6,3) - , 00: 08:273 (2.4) - , 00:15:293 (2.6) - , 00:19:976 (6,5,6,5) - , etc. In short, you have to listen to the song well, where those strong ones are, when the song slows down, and so on to give it good emphasis with the spacing or changing the sv.
There are parts like in the chorus of the song that has parts like 00:15:586 (1,2,3,4) -, 00:16:757 (1,2,3,4,5) -, 00:20 :269 (1,2,3,4,5) -, 00:22:610 (1,2,3,4,5) - which can be made much more intense, however there are other parts where the intensity is similar or greater than kiai as 00:36:079 (1,2,3) -, 00:38:421 (1,2,3,4,1,1,2,3,4,5,1,2,3,4,1,2,3,1,2,3,4,5,6,7,8 ,1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8,1 ) - , etc. Basically what you can do is make those parts more intense or less intense depending on the song since having a similar spacing in part of the map makes it not feel intense and monotonous, for example from here 00:38:421 to 00:43:104 You can make that part of the kiai since that part can be heard and is very intense, the same could be in the other section here 00:47:778.
also improving and making better patterns since there are parts like 00:03:299 (1,2,3,4) - , 00:04:766 (1,2,3) - , 00:07:980 (1,2 ,3,4,5,6,7,8) - , etc. which can be polished more and helps improve the quality of the map.
Maybe for a beginner mapper it's not bad at all, good luck improving and learning from mistakes for your next maps^^
I'm not sure if you already change this or not but i still heavily agree with this, your diffs are the weak point of this mapset (i'm sorry but i need to be honest) and its probably not gonna be rankable because of this huge difference in quality.
Emphasis and visuals are something that you will get it with time, but if you want to learn faster pick any ranked map that you like, try to see in the editor when the map (not the song, the map) is lower or higher in terms of spacing and density, then try to find the justification of that in the song. For example:
00:00:958 (1,2,3,4,5,6,7,1,2,3,4,5,1) - when you mapped like this, you basically set a "standard" that the lower intensity of the song will be spaced like that.
BUT
00:15:586 (1,2,3,4,5,6,1,2,3,4,5,6,7,8,9,10,1) - you mapped like the song just increase is intensity by like 5-10% while there's literally the guy almost screaming at you ear (quite the difference in intensity comparing with the secton mentioned before)
I hope i didn't discourage you to map with this, but you need to face this problem in order to get you first rankable map
