Hummmmm a lot of rebubbles on this...anyway here are some suggestions to look over
-Make sure the start/end of all of your kiai times are snapped on every difficulty (for some of them they are snapped on the blue tick before the note which doesn't look good while playing etc)
-I would expect some sort of hitsunds at places like 01:00:410 and 01:50:642 etc on every difficulty where the backgroud pulses just to emphasize those parts more
-Your first BPM sounds pretty early towards the end of it, I would try and get your timing double checked again if possible
-For the map starting straight away (even if it is a spinner) I would try and include more than a .5 audio lead-in
-Seeing as the first 2 difficulties are both made by you (I think?) the kiai on them needs to stay consistent
-You need to include an approach circle in your folder to go with your custom hitcircle/hitcircle overlay
Dance:
-The kiai should start at 02:35:333 like the other difficulties have it to start on the main part of the chorus instead of before it
00:17:154 (1,2,3,4) - this could be more creative than just being stacked in 1 place
00:22:735 (1,2,3,4,5,1,2,3,4,1,2,1,2,3,1,1,2,3) - combo placement here seems to change randomly, try and make them follow a consistent pattern
00:39:828 (6) - new combo to follow your next pattern
00:59:014 (1,3) - why not stack these? It doesn't look good while playing at the moment
00:59:014 (1,2,3,4,5) - I would expect hitsounds here to match the other parts of your map where the song gets louder (same for places like 01:50:642 (1,2,3,4)
02:39:868 (5,6,1) - keep your spacing equal here
Wild:
-This difficulty sounds much quieter than the other currently difficulties have doesn't fit the song as much, I suggest you raise the volume on almost all of the sections slightly (the volume of the map compared to the song sounds the best on 'Dance' at the moment)
00:11:572 (1,2,3,4,5,6,7,8) - personally I would expect claps or something on these like the other difficulty
00:28:316 (1,2) - kind of odd anti jumps in a place like this, try and space them out more
00:31:107 (1,2) - ^
00:52:037 (1) - remove new combo
01:26:572 (4,1,2,3) - the spacing on all of these shouldn't really be the same
01:32:851 (1,2,3) - nazi: patterns like this could look much nicer by making them match each other more
02:10:177 (5,1) - space out more
02:24:170 (2) - lower this slightly so it doesn't go through the HP bar
Aleks' Rhythms:
-I find it strange that you choose kiai time to use 0.75 slider speed, I would expect kiai to go faster than the mapset in general not slower
02:42:310 (1) - very close to being silenced, try and raise the volume on it slightly more
Nivalis' Rhythms:
02:42:310 (5) - same as Alek's
Overall the mapset is fairly well put together, I suggest you try and get a few more mods before a rebubble just to polish things off more though
