Hi! Here's your requested mod.
[Relaxing]
01:35:664 (2,3) - (nazi) you could move the red point of (3) a little bit to the right for a nicer blanket -
http://puu.sh/6N7Z2.jpg01:56:487 (4) - normal sampleset sounds a bit awkward here, because the beat in the music is not that loud, I think a sound from drum sampleset would fit better, for example finish or anything you think would fit
01:57:193 (1) - this plays weird because the beat in the song starts earlier, so you should start this slider earlier 01:57:017 - and lengthen it -
http://osu.ppy.sh/ss/131551501:58:958 (3) - this slider is too long and doesn't fit that well to the beat, it should be like this:
http://puu.sh/6N8cw.jpg - but if you don't want to change it at least use soft sampleset at the end of the slider, since the music is not that loud at the point where you end the slider
02:07:781 (4) - same here about using soft sampleset
02:50:487 (2) - it is annoying that the slider starts later than the lyrics so I would suggest something like this:
http://osu.ppy.sh/ss/1315530[Average]
01:52:958 (4) - this plays really weird like this (even though I guess you just wanted to make it simple), however I think that this could be also simple and would sound better -
http://puu.sh/6N8Pw.jpg OR
http://puu.sh/6N8Pc.jpg01:56:840 (3) - this one is also awkward because you start the slider earlier than the beat, I can hear the soft beat in the background but it's not loud enough to start a slider and you also focus on the loud beats so you should follow the loud beats in my opinion, this is what I think would fit -
http://puu.sh/6N91B.jpg - having (6) on the white tick also sounds weird, so I hope you consider these changes
[Difficult]
00:34:134 - add a hit circle so that you follow this pattern? - 00:33:428 (4,5) - the lyrics go just as fast as here
01:41:899 - same reason as above ^ and I also think that the flow will be better because you don't end mapping to that fast lyrics abruptly (if you add the hit circle)
01:56:840 (3) - it is kind of annoying that the beat is in the middle of the slider, so you could maybe divide it like this? -
http://osu.ppy.sh/ss/131561501:59:311 (2) - this should be earlier 01:59:134 - since the beat is there, I can see that you're just trying to create a somewhat "easy" pattern, but it sounds weird since the hit circle is too loud when the song is soft, so if you don't want to change it at least use soft or drum sampleset or something that is not as loud
02:28:487 - add hit circe for the same reason as the previous ones?
02:33:075 - add hit circle here too because the music has this kind of melody which I can't really explain, but the hit circle would fit a lot to the song and flow could be better too if you added it
02:45:428 - add hit circle for same reasons and you also do it nicely here 02:48:605 (5) - and this part is similar to the one I pointed out so it should be fine to add something
[Tough]
00:07:781 (3,1) - why did you use higher spacing between these? you should put them closer
00:29:193 (3) - I think you shouldn't start the kiai with a slider end, I think something similar to this could also work:
http://osu.ppy.sh/ss/131564501:17:399 (1) - use soft sampleset here? because the spinner doesn't end on anything loud
01:56:311 (8,1) - use drum finish at the end of the slider and on the hit circle? since you seem to hit the soft beat in the music that's why the hitsound shouldn't be so loud

01:59:311 (10) - ^
02:03:723 (8) - add NC? because this combo is quite long and because the melody in the song changes a little bit (but it's too hard to explain exactly what sound changes)
02:06:546 (8,9,1) - why not use the same distance for the stream as 02:05:840 (3,4,5) - ?
02:16:781 (10) - add NC because it's too long and because he starts singing a new "line"?? well it's hard to explain but it sounds like the "I" starts a new section
[Challenging]
00:29:193 (3) - the same that I suggested on Tough, try not to start the kiai with a sliderend, and you don't do start the kiai with sliderends at the similar parts of the map
01:17:311 (1) - why don't you add a hit circle just like you did here? 02:20:840 (1,1) - it would fit to the beat
That's all, it's a very nice mapset so there is not much to say, good luck! :3
