Forgive my bad English, I don't know how to say some expressions, so I will use a translator to help me express, there may be some inaccurate parts. I will use more pictures to express my thoughts.Please forgive me if my words offend you, I didn't mean to, I just can't express my politeness.

It would be better if you use Simplified Chinese.

Lovely music, and a fun LN design. I think you're very good at designing for vocal, I may not be able to offer better advice in this part. However, I have some different views on your design of the drums, but this may be contrary to your original intention of the difficulty. So I will present discussion forum for reference later.

Oh, I really like how different authors express themselves different thinking on grace, but this can be a very subjective design, I am not sure whether I can offer you constructive advice on the design. I have some scattered ideas, give me some time to sort them out.

The sv kind of scared me, I'm really bad at that. I'll take a look at what you've mentioned though, maybe some simple modding.

Good song, with you clean structure, modding later.

Nice song to mod, still have some problem in consistency of vocal, modding later. Maybe mod the insane, same problem in other difficulty, so less further elaboration.

A selection and writing style that I found surprisingly interesting, but I'm probably not very good at such creations. I still like this LN creation and I will try to provide some of my personal views afterwards.

25時好啊。感觉比较风格化的写法，我也有一些比较个人的想法，希望能让它变得更有趣，之后细看一下，rc上就不多看了应该问题不大。

I have to say my playability isn't up to this map, but it's still a nice design. Will mod it later, but I probably can't give very comprehensive advice, hope you don't mind

I'm very sorry, but I have to say that using this music to write a map might be a bit difficult for you. The melody is unconventional and the sound design is a bit complex. I'm sorry to say that the design of the map is a bit detached from the music. Maybe you should choose something with a more conventional rhythm for your early attempts, and try this music later when you are familiar with the RC and have some understanding of the composition.

I'm sorry to say that I'm not a big fan of similar single-design maps, which are usually use as exercises, I'm not very good at suggesting them. So, I express my opinion here: I think the consistency is generally up to standard, but the balance of difficulty is not so good, the variation in difficulty somewhat exceeds the variation in intensity of the music, and the individual minijacks in the second half of the piece are a bit abrupt. And in terms of richness I think there is still a lot of room for improvement, so perhaps you could seek out some authors who are good at writing jacks to study, and design variations over a longer range.

It's a really big project and I'm sure you have your own opinion and purpose for such a choice, and I'm sure you have experience with this. For me personally, I do not reject groupings, but I might feel that the difference in difficulty of the content is too big. It may not matter for a single song, but this album has more similar music while a greater difference in difficulty, it looks like a patchwork of separate maps, which I don't really agree with. Still very sorry for can't giving you a suitable opinion, it's just because our perceptions are different, my opinion may conflict with your original intention.
