m4m from your queue :< NOTE: I am on my laptop now, so I can't testplay maps because of the massive lag and so my mod can be wrong, sorry for that :/
yanlu's Easy00:23:286 (3) - It's only a detail but this slider can be improved maybe
00:33:104 (4,1) - This blanket can be better, use the previous object's approach circle for helping you!
00:34:558 (2) - A normal curve? I appreciate the creativity but this is a bit odd
00:36:740 (2,3) - Blanket
Rainbow's Normal00:02:013 (2) - You can try to make something better instead of a straight slider, maybe. Also, move it 1 grid up
00:04:922 (2) - ^ (Don't move it 1 grid up)
00:09:468 (3) - Use ctrl+g on this, it flows better
00:16:740 (2) - Last sliderpoint 1 or 2 grids up
00:32:377 (2) - Move it 1 grid up or down for a better-looking pattern
00:41:286 (5) - Move 1 grid right
01:15:468 (1) - The next object is a bit too near to the spinner... You have two options: First: You end the spinner 1/1 earlier or Second: You make this 01:17:104 (1) start near to the center, so the player can reach it easier. I suggest the second...
Hard00:43:649 (4) - Ctrl+g would be better because of the flow, but you will have a little jump with the following note
00:45:013 (8) - I suggest to remove this note, this is the only triplet in the whole diff, so the player, when he/she sees this, can get confused. So, remove this note
Insane00:04:013 (2,1) - This is really, really flow-breaking... The next slider should be like this, in order to have an oval flow
01:01:649 (3,4) - Select both notes and use ctrl+g for a better flow
01:10:195 (4,5) - The same
01:18:195 (4) - Clap
01:28:740 (1) - This is 5% volume, so it's not audible. Remember: All objects MUST be audible, except for spinners, so this note is unrankable if you don't raise the volume and make it audible!

That's all, the map should be ok for bubble, I just suggest to improve some sliders in the Normal, bye!
