Hi BB! Random Bubble check! 
(And this is my 4th BAT mod) [Xin's Easy:]
• 00:09:733 (2) - During the gameplay, it feels slighty better if you move this note down of the Sliders (1,3). I mean, move (2) to
x:256 y:216• 00:15:805 (2) - The high pitch in this part is in the Vocals, the instrumental sounds really slow in this part. In my opinion you should emphasize the Vocal here, to do that reduce the Slider length in 1/2 (your slider have to finish in 00:16:340 + Repetition). Plus, if you want you can add a Note in 00:17:233 and would be good if this Note has a New Combo
• 00:34:019 (4) - The whistle in this note doesn't sounds really fitting to me. Can be a good idea if you remove the Whistle and add a Clap instead if you want to have this note hitsounded.
• 00:34:376
(Spin) - This Spinner have to finish 1/2 back, because it is the place where ends one part of the voices and start the new one, check this properly and you will notice that. I highly suggest you to fix that
• 01:11:519 (1) - Reduce the Slider length in 1/2, will follow better the Instrumental. Remember that you can use the red (1/2) ticks in this kind of Sliders if you want, a fully 1/1, 2/1 easy it is kinda boring in general, then add a Note with New Combo in 01:12:948
• 01:20:090 (1,2) - Fits better with your symetry and with the music too, if you swap the combo placement in these Notes. I mean, Remove the New Combo in (1) and add it then in (2)
• 01:39:019 (2) - I think that you are missing a Clap in this Note.
• 01:45:805 (4,1) - The Spinner is pretty short to be placed in an Easy diff. I think new players will not the necessary time to react. I think is better if you remove the Note and move the Spinner till there. Then, your spinner have to finish in 01:47:233
• 01:48:305
(x) - Hmm.. Add a Note to follow better the Vocal?
[Normal:]
• 00:22:233 (2) - A Clap at the Slider end fits with everything in the music in my opinion. You should consider adding it. Btw, you did that in 00:50:805 (2), so would be consistent too.
• 00:34:555
(Spin) - Exactly the same as Easy, this Spinner have to finish 1/2 sooner.
• 01:11:519 (1,2,3) - This pattern flows bad to me, but I couldn't find a good suggestion. If you can do something by yourself would be great.
• 01:31:519 (1,2,3) - This reversed pattern can cause confusion in an average player, I think that they won't percive properly (3), because of the stack, so try moving (3) to other place
• 01:32:948 (1,2,3) - (^)
• 01:34:376 (1,2,3) - (^)
• 01:36:519 (3) - The Clap at the Slider end sounds bad to me, maybe you can remove it from there
• 01:44:376 (3) - Add a Clap at the Slider end, is necessary because appear in the music
• 01:45:805 (1,2) - And here, remove the Clap in (1) (it sounds pretty bad imo) and add it at the beginning of (2)
[Hard:]
Settings:--> The Approach Rate looks kinda low at the time to play the map. Increase it by 1 Tick please (AR+1)
• 00:20:090 (1,2) - Increase a bit the flow if you try to do something like this:
• 00:34:555
(Spin) - Same as previous difficulties.
• 00:45:805 (1) - It is a Hard difficulty, and in my opinion the beat in 00:46:162 needs an emphasize. I think your Slider (1) have to finish in this place and then add a Note in 00:46:340
• 00:47:233 (5) - (^)
• 01:16:519 (7,8) - Ugh.. this flow bad, for a better flow move (8) to
x:424 y:268 - Nice . Maybe you can spaced out a bit more your 1/4 3-plet, but this is a personal 'like' I'd say, it is up to you if you want to fix it or not.[Insane:]
• 00:34:555
(Spin) - Same as previous difficulties.
- Nice and Simple diff. I liked it :3. Again, maybe you can spaced out a bit more your compressed 1/4 3-plets.And, that's it..
Poke me afterwards for a recheck
Thanks! To the other suggestions no sorry ;w; because i find these better how they are!
