1. Chiisana no Uta (4.86 stars, 756 notes)

1. The song sounds so much like dango daikazoku, it may be a good idea since this tag is related to the song for sure.
2. Please, disable letterboxes during breaks. It makes no sense to keep it enabled, there're no any breaks, after all.

1. 00:01:368 - ignoring 1/2 beats feels rather uncomfortable. At least try to point it out by curving the slider like you did it with 00:04:939 (1). Iit plays rather confusing and a bit unpleasant as it is now, imo.
   Note: 00:04:939 (1) - whoops, the same here. Please, do the same thing to both of these sliders, so we'll make your patterns a bit more consistent, which is awesome, imo.
2. 00:16:844 (1,2,3) - please, spend some time to get your blalankets cleaner and patterns neater. Here's an example!
   Note: try to spend some time, like ~30 minutes or so to clean up the diff in general. I like your ideas and I see how they work, but some of them look a bit unidy and can be easily improved visually.
   Note: 00:36:129 (2,3,4) - uguu, blankets are awesome.
3. 00:24:939 (3,4) - at such parts, the transitions feels weird comparing to the rest of the map where your flow is amazing and really smooth. here's an example of what you can get
4. 00:45:891 (7) - the slider looks EXACTLY like the previous ones but it has more repeats which is totally unexpected and rather hard to understand. Consider breakiung it into two sliders or pointed the slider out with a new combo to make it more understandable!
5. 01:24:939 (3,5) - please, unstack the slider manually to make it more readablee and playable with some modes like Easy/HT. With these modes, the second slider may become pretty hard to notice and bug players.
6. 01:51:606 (5) - the 3/4 slider sounds pretty weird due to the beat ignored at 01:51:844 - try to finish the slider 1/4 earlier or you can try to use the red anchor to emphasize the beat. Either way is fine imo.
   Note: same applies for the sliders like 02:00:177 (3) - and some others.
7. 02:02:677 (9,11) - sounds like you're overmapping a bit. Please, try to remove them in order to reflect the music better and to make your rhythm more precise.
8. 02:34:463 (3,4) - I do not think that the 1/4 gaps here sound quite good. I understand your point, but the music is going calm there, so, I want you to make the sliders 1/4 shorter. They will end on the red ticks, which will match with the music a bit better and fit with the song's tempo a bit better.
9. 03:00:177 - don't you feel bad about the beats being ignored here? Why don't you try to map the beat here? It sounds like a good idea to me and I feel like it may fit here.
10. 03:18:987 (1) - your comboing feels a bit broken here. Tty to remove a new combo, please. It looks a bit unnecessary.
11. 04:00:415 (2) - minor - your flow here could be slighly improved if you move (2) down. It will give a smoother and more natural transition.
12. 04:37:320 (1) - the jump here feels too far and does not really reflect the song. Please, try to reduce the DS here, it will make the diff a bit more playable and logical. I think that this jump does not really fits with the diff.
    Note: 04:42:558 (4,1) - same happens here. Though this one does not feels THAT hard, it is still a bit exaggerated.
    
    The diff is quite good. I do not really like a couple of your patterns, but it's based on my personal preferences and opinion. You did a great job, but some polishing would help you to make it even better!
