Hi! Time to mod your map 
[Easy:]Settings:--> I know that it's an Easy difficulty but the Approach Rate feels a bit low, would be better if you increase it by 1 Tick (AR+1)
• 00:02:796 (2): This Slider is not to funny to play because doesn't follow a significative thing in the song, especially in this Easy. To follow better the Rhythm you should make another thing. I look for a lot of varieties listening the music in 25%, and the best one that I could find it is if you move this Slider to 00:03:030 and this Slider should be in 1/2 (Finishing in 00:03:264) and after that add a Repetition (It's much better if you change that for a better playability, if you can find another idea better than mine it's Ok too :3)
• 00:06:546 (4): (^)
• 00:11:702 (3): In the middle of this Slider (After to the Repetition) the rhythm change, for this reason this can't be united because doesn't follow the Rhythm in all the aspects and this make a weird thing with the Rhythm. To follow better the Rhythm you should remove the Repetition and then add another Slider that Starts in 00:13:577 and finish in 00:14:749. You can try something like that to don't have any kind of Spacing Problem:
SPOILER
180,120,11702,2,0,B|128:66|67:55|7:125|10:184|45:230|97:240,1,300
52,332,13577,2,0,B|88:404|177:381|221:301|158:247,1,250
260,256,15218,5,2
• 00:22:718 (1,2): In this case is better the consistent than the Symetry. It's better if you keep consistency between the Sliders (2,3) following the Vocal. For this reason I suggest you to remove the Note (1) and then move the Slider (2) to here. Works better in my opinion.
• 00:26:468 (3): To Remark the Vocal (This 'uhh') it's better if you add a Whistle on the Reverse Arrow as you did it at the beginning
• 00:44:749 (1): In the music appear a sound like a Clap hitsound for this reason sounds preety fine if you add a Clap in this note to emphatisize this sound in the music
• 00:51:311 (3): I prefer to do another thing to follow better the rhythm, I think that this Slider end on a Red Tick doesn't work at all. For this reason it's better if you do 2 Sliders in 1/1. The first one (3) starts on 00:51:311 and finish in 00:51:780 and the second one (4) starts on 00:52:249 and finish in 00:52:718.
• 00:59:632 (T): To be consistent with Normal diff. (where sounds better) add an Inherited Timing Point here with 40% in Audio (Do that if you don't follow the next suggestion)
• 00:59:983 (1,1): The Slider is too Close to the Spinner to be on an Easy difficulty, this is difficult to New Players, in general is difficult to make the spin and more if you are thinking on a Slider then. Maybe you can reduce the lenght of the Spinner to make this pattern easier
• 01:15:218 (1): (NAZI)- This Slider can be better if you curved it a bit more
• 02:03:499 (1): A Clap fit perfectly here, if you listen the music appear a sound like a Clap here too.
• 02:18:733 (1,1): Same as 00:59:983
• 02:47:561 (4): I think that you have to reduce this Combo a bit because is a bit long to be in this difficulty. Following the Voice, here is the better place to add a New Combo
• 03:00:452 (1): Add a Clap at the end, same reason as 02:03:499
• 03:03:030 (5): And here add a Clap at the beginning of this Slider
[Normal:]• 00:03:968 (1): Looking your previous pattern, this Slider in 1/1 doesn't work at all, sounds empty at the hour to play the map. I think that you should follow the same consistence as before, to make that Reduce this Slider by 1/4 and then add a note in 00:05:022 (on a blue tick), can be a bit difficult because appear a Note on a blue tick but looking the difficulty in this beginning it's Ok in my opinion
• 00:49:905 (3): I personally don't like how to play this Whistle on Sliderbody for some reasons. First of all is inconsistent with the rest of the map because you never used this kind of things in the Whole of the map and then you don't have nothing to emphatisize with that, so this make the Whistle unnecesary. It's better if you remove it from here
• 01:12:405 (3): For consistency with all the 'uuhh', you should add a Whistle instead of a Clap on the end of this Slider. Also, on Collab you did that
• 01:25:061 (5): I'm preety sure that you forgot to add a Clap on the beginning of this Slider
• 01:27:874 (3): Add a Whistle at the beginning of this Slider (same reason as 01:12:405)
• 01:31:155 (2,3): The Reverse Arrow on these Sliders don't follow nothing in the music and for this reason sound bad. For this reason it's better if you Remove the Repetitions on each Sliders and make them in 1/1, here an Screenshoot to avoid any doubt:
• 01:55:330 (x): I think that work better with the Vocal if you add a Note here.
• 01:55:764 (1): The Whistle on the Sliderbody doesn't work fine here, would be better if you Remove it from here
• 02:12:405 (3): If you following the music properly, you have to add a Clap at the end of this Slider because appear something like a Clap in the song. For this reason, it's better if you emphatisize that
• 02:37:718 (1,2,3): In General, Slider Stacked (like that) don't make a good sense because don't look fine at all. Also, this kind of things are a bit difficult to 'Normal' Players. For that, this pattern would have a better flow if you unstack those Sliders
• 02:48:968 (1): For consistency with your other difficulties, you have to Remove this New Combo
• 03:24:593 (1,2,3): Same as 02:37:718
• 03:35:843 (1,2): This pattern in particular doesn't follow the music in any aspect, I could find a simple thing in 1/1, without any kind of weird thing that fit properly with the music. The Slider (1) have to start in 03:35:843 and finish in 03:36:780 and the Slider (2) starts on 03:37:249 and finish in 02:37:718, Here you have an Screenshoot.
[Collab:]Bourdon:• 01:33:733 (2): The Normal Whistle at the end of the Slider sound noisy, and doesn't fit at all with the music. You can fix that replacing the Normal sampleset to a Soft samplset, sounds much better in my opinion
• 01:39:827 (7): (NAZI)- Just for esthetic, because looks better, would be a good Idea if you Curve this Slider a bit like the previous Slider (6), maybe a Copy/Paste is a good idea. Try it, you will look that looks better and you don't have to do a lot of things after that (To be sincere you don't have to make nothing after to Curve the Slider
)
• 01:42:874 (6): For consistency, you have to add a Whistle in this Note
• 01:55:296 (1,2,3,4,5,6,7): We have to consider that this difficulty is a Hard diff. in general is not recommended to have a Stream with more than 5 notes in this kind of difficulties. If you want you can keep that, but try to compress a bit this Stream making the distance smaller.
• 01:55:999 (7): This Note need a Clap, fit perfect with the music
• 02:03:499 (1): (^)
• 02:10:882 (x): In this Section you are following the Instrumental and the Vocal a lot. To continue with that and don't break the consistency, it's better if you add a Note here.
• 02:16:624 (9): I can percive a more reasonable Stop on here if you Replace the Slider to a Note in this position. Try to listen the music in 25%, I think that it's better
• 02:33:264 (4,5,6,7,8,9,1): As I explained before, this 7-plet should be compressed, making the distance between notes smaller
• 02:35:374 (8,9,10): Wait... A 3-plet here? There is nothing in the middle where is (9) to be remarked with a note, there is no Rhythm in the music, so this is consider as a overmap. Remove (9), is more benefit to the Rhythm.
• 02:48:499 (8): You are missing a Clap at the beginning of this Slider
• 03:52:718 (1,2,1): These Sliders are Silenced a lot, but anyways I can listen the end of them and they are very unnecesary to the music and sounds totally off-Rhythm. For this Reason it's better if you change these Sliders to 3 Notes on the White Ticks, sounds in the Music perfectly and don't make a bad sounds like the Sliders at the end.
Roddie:• 00:04:319 (2): If you listen the music (Inclusive in 25% to be more sure), you don't have nothing here, and it's better to delete the Overmap because this kind of things make the difficulty much more difficult than Normal.
• 00:08:069 (1): (^)
• 00:11:350 (5): You can make a paused more remarked here, because if you listen the music the pause is there. To make that it's better if you change the Slider to a Note in this position
• 00:44:632 (x): A note, to be more consistent with the another 3-plets
• 00:44:749 (2): And you're missing a Clap here
• 00:45:686 (4): (^)
• 00:59:632 (T): I prefer to listen something in the Slider, there is a little sound in the music. For this reason, I think that you should increase the Volume to 40% (Like Normal diff.)
• 01:03:030 (2): This Clap sounds bad and doesn't follow the Pattern of Claps that you have in the mapset. It's better if you remove from here
• 01:05:608 (8,9): I prefer an antijump here, and I'll said you why, After that you have the jumps in 1/2 when he said 'uu' bla bla bla. This kind of things can be a bit confusive and you can remark this space in 1/1 with an antijump, is the better option in my opinion
• 01:18:382 (x): A Note to be consistent with your 3-plets
• 01:18:733 (5,1): You should make an antijump between these Notes too. (Same as 01:05:608)
• 01:25:061 (3): Add a Clap on the beginning of the Slider. Same reason as always
Well, That's All. The difficulties are preety fine but I don't like the gap of difficult between Normal and Collab. I think that it's preety big inclusive on the Score, try to checks out that, otherwhise the maps looks preety fine.
Star to show you my support and the Best of luck with this map, Bourdon! 
Add "single" to tags.
Why you don't use loops? it makes code more clear and readable.
