First, you rely on simply putting a sound on a constant rhythm throughout most of the songs, which does work for some maps but doesn't work for maps that are based on irregular vocals or instruments.
Also, you seem to overmap often with streams or with triple stacks.
And finally, you have a huge variety of songs here, but you don't seem to vary up your own mapping accordingly.
Mods00:24:894 (1,2) - Doesn't fit the music
00:27:560 (6,1,2,3,4,5) - ^
00:28:060 (5,1,2,3,4) - ^
01:00:727 (1,2,3,4,5,6,7,8) - These sliders don't seem to be following the vocals, which almost all of your previous sliders do
01:28:227 (3,4,5,6,7,8,9,10) - Your previous steam into a slider does work since it has an audible sound playing for the notes, but these seem to represent nothing
01:38:310 (2,3,4,5,6,7,8,9) - Again, the sliders don't seem to follow anything
02:10:727 (8,9,1) - Follows nothing
02:21:643 (8,9) - These last two notes extend the stream longer than needed
02:28:227 (1,2,3,4,5,6,7,8) - Overmap
02:29:643 (2,3,4,5,6,7,8) - ^
02:30:894 (1,2,3,4,5,6,7,8) - ^
04:02:810 (1) - Remember that spinners end in a beat, so you might want to extend the slider so it does this circle's job: (04:03:560 (1) - )
04:04:060 (4,5,6) - Overmap
04:05:226 (1,2,3,4,5,6,7,1) - ^
04:08:560 (1,2,3,4,5,6,7,1) - ^
04:10:310 (1,2,3,4,5,6,7) - ^
04:12:560 (7,8) - Your last two double stacks follow the drum fine, but this doesn't
04:13:143 (2,3,4,5) - Doesn't match vocals
04:14:226 (1,1,1,1) - While these sliders are fine, I would suggest replacing the first two or three with streams instead and a slider to land on
04:16:893 (1,1,1,1) - ^
04:20:560 (1,2,3,4) - You could replace these notes with a slider, but it's otherwise fine
04:25:893 (1,2,4,2,3,4) - These notes seem to be following the beat but the others or following the vocals
04:36:060 (4,5,6,7) - Sliders could be matched up with vocals
04:36:893 (9,1,2,3,4) - Overmap
04:37:726 (7,1,2) - ^
04:39:560 (9,1,2,3) - ^
04:41:060 (8,1) - ^
04:41:893 (6,1,2,3) - ^
05:04:560 (4,5) - The two hitcircles could become a slider to represent the singer's voice more accurately
05:04:560 (4,5) - A stream here would be more fitting since there is a drum sound in the background
05:07:560 (4,1,2,3,4) - A long slider can replace all of this
05:08:893 (8,1,2,3,4) - ^
05:33:226 (3,4,5,6,7,8) - You could map the circles to the vocals instead of placing a stream
05:36:393 (1,1,1,2) - What are the slider ends supposed to follow?
05:39:560 (1,2) - Transition is nice, but from this point onwards you don't seem to follow the obvious voice of the song
06:07:310 (1,2,3) - A stream could be used here
06:10:060 (3) - Slider is off play area
06:15:435 (1) - Should be a hitcircle
06:15:435 (1,2,3,4) - A long slider would fit the voice
06:15:435 (1,2,3,4) - ^
06:16:435 (4,1,2) - ^
06:23:060 (3) - An attempt was made to make this like zigzag
06:23:685 (1,2,3,4,1,2,3,4) - Sliders do not reflect voice
06:27:810 (1,1) - You should make it so the player needs to do streams between these sliders, otherwise this is a sudden drop in difficulty
06:31:060 (2) - zigzag?
06:38:435 (5,6) - Doesn't fit vocals
06:41:185 (6) - Not needed
06:42:810 (7,1,2,3,4,5,6,7,8,9) - Awkward transtion from a jumpy map into a stream
06:46:310 (1,2) - Doesn't match vocals
07:08:185 (2,4,4,5) - Random skips that are not needed
07:15:685 (1,2,3) - Sliders are too long and slow to fit music
07:16:435 (4,1,1,1,1,1,1,1) - Stream starts too early and is overmapped
07:16:935 (1,2,3,4,1,2,3) - Sliders don't match with music
07:18:685 (4,1,2,3) - ^
07:19:685 (4,1,1,1,1,1,1,1,1) - Not in sync with music
07:20:435 (2,1,1,1,1) - ^
07:20:935 (2,1,1,1,1) - ^
07:21:435 (2,1,1,1,1) - ^
07:23:622 (1,1,1) - You don't have to have sliders covering the whole stream, but use them as breaks in a long stream to lower the difficulty to one that matches the whole beatmap
07:26:435 (1,2,1,1,2,3,4,1,1,2,3,4,1,1) - Doesn't match with music
07:33:435 (5,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1) - Overmapped
But then again this is my first time modding so don't trust any word I say.
