gonna give you some things to work on. hope you do not mind.
Insane00:01:941 (1) - reverse arrow not snapped to a sound when it can be. snapp it to the next red tick
00:03:204 (2) - ^ same as before but the sound is on the red tick before the arrow. shorten the slider and add a circle
https://puu.sh/va4Bs/bc92f99ba9.jpg00:04:625 - try to map this sound, it sounds simuler to 00:03:204 (2) - so use the same pattern. so the first line should can look like this
https://puu.sh/va4Bs/bc92f99ba9.jpg 00:06:046 (1) - not snapped to a sound. The opening has one strong instrument that players follow so every object should be snapped to a sound.
00:07:625 (4) - not snapped to a sound.
00:10:782 (5,6,7,8,9,1,2,3,4) - this is unreadable. you can't space object like this. i recommend 00:10:782 (5,6,7,8) - change 5,6 in to a slider have 7 be a bit away from the slider end, then let 8 have a bigger spacing because you are emphasizing this sound. Stack 9 under 8. you do this when you change from a half beat object to a full beat or longer.
00:12:204 (4) - try to avoid placing sliders on a red tick
00:14:888 (3) - do not reverse arrow this.
00:16:783 (7) - move this so it's on the slider end, i think this looks better
00:17:414 - distinct sound that is not mapped? consider mapping it.
00:18:677 (4,5,6) - here you can use something called time distance equality (TDE). this is where the distance between 2 objects are proportionate to the distance on the timeline.
00:21:361 (8,9,10) - try to avoid over mapping
01:12:644 - missing Kiai
try to keep New combo on the big whit ticks
What i have said over are problems that happens further in to the map. however i'm not gonna list them all here. this is because i want you to try and spot them on your own. it might be hard at first but it is one of the fastest way to learn. rather than me telling you the same problems that keep popping up. if you are struggling to understand my mod or you want to double check that you have ironed out the big flaws, shoot me a pm.
GL and keep on mapping
