hi. my mod will be mostly general advice since i feel you still require some experience in mapping, sorry
general-add in more audio lead in, recommended 200ms, while u currently have only around 700ms
hitsounds-applies to all diffs, what i am going to say
you're hitsounds are all over the place, they're quite random and follow no pattern, usually for claps would be on the offbeats, every 2nd & 4th beat in a measure of 4/4, whistles would be on the first/ third beat, this hitsounding technique creates the effect you hear in most songs, even this one (listen to the chorus for example) . finishes are self explanatory for they go on emphasized sounds like 00:01:700 - 00:08:024 - and more, for example. of course you dont have to follow this pattern completely at places like 00:04:781 - where the drum doesnt exactly follow the pattern. but this applies for most cases
insane-00:02:511 - it'd be better to remove this, theres no note on this beat in the music unlike places like 00:02:348 - , by doing what you currently have you lose the emphasis of the drum
-00:05:754 - better to follow drum here?
-00:09:484 - you ended this slider tail on a strong beat, which doesnt feel good since its not clickable and its really emphasized in the music better to make it clickable like a slider head or circle
-00:15:159 (3) - passive sliders arent always bad, but you chose a bad place to put one. since the emphasis of the piano is right on the tail, making this slider sound awkward
-00:17:754 (2) - should actually start at 00:17:835 - if you pay attention to the drums, yes this blue tick would be awkward to click so trying something like this would be appropriate here
http://puu.sh/gWYak/8215b471e4.jpg-00:19:051 (8,9) - this is a bad usage of spacing, its hard to tell they are 1/1 apart, try stacking instead
-00:26:997 - missing this beat is just awkward, you were following it before then you randomly stop, same with places like 00:26:511 - , 00:29:105 - ,00:29:592 - and more, it drives the player off guard
-00:47:321 (4,5,6,7,8) - a 1/3 stream is really unexpected, players will think this is 1/4 just out of habit, 1/3 repeat sliders would be better imo
-01:11:755 (1,1,1,1) - whats with all these nc's? i dont get the point of these since they don't really fit here for me
hard-just a quick tip but usually 1/2 in hard aren't spaced like 1/4's in hard, its confusing because especially in the beginning & end, players may interpret your 1/2 notes as 1/4
-00:26:024 - for these notes i'd suggest mapping the instrumental instead of the beat since the instrumentals are most dominant here, even though you're following the beat it feels off not following the dominant sound
-00:39:321 - this shouldnt be 1/4, if you listen to the music at 25% theres definetely no triplet here
-00:45:809 (1,2,3) - equal spacing please
-01:03:971 (1,2,3,4) - ^ distance snap works nicely for these parts hinthint
normal-i disagree with your usage of 1/2, they all aren't used ''correctly'' i mean, for music theres always going to be a base beat, usually weak ticks on 1/2, but you use your 1/2 rhythm to follow those instead of the actual instruments playing in the song, doesnt play in a rational way imo
-also remember to use distance throughout the whole song, with little to no exceptions, i noticed at parts like 00:17:754 (2,3) - 00:14:673 (1,2) - 00:15:971 (1,2) - you turned it off, dont do that please, you can use a higher grid if you have trouble stacking
-keep your new combo's consistent, stick to one pattern (id suggest 1 nc every second measure) stuff like 01:03:971 (1,1,1,1) - shouldnt really be in normal
easy-keep distance snap consistent throughout the map, and i'd suggest a distance that wont make notes 1/1 apart overlap each other, you can easily notice spacing inconsistencies in parts like 00:50:998 (1,2,3) - (and many more throughout the map)
-00:25:051 (1,2) - pathway isnt very clear, may be questionable to some qats i dunno
remember i only gave you general points/ tips stuff, my mod isnt really a 'reply line by line' i hope you will take in these and actually fix stuff throughout the map if you want to improve it,looking at recently ranked maps to see how they are constructed is a good idea too like celsius said
well good luck
EDIT: sorry dont mind the stacks stuff i forgot to enable stacking
EDIT 2 : for audio lead in i made a typo, supposed to say "2000" not "200" lol
