Hey~
No kd for this post, I'll be doing a more extensive mod later, I just first wanted to point out some of the obvious "unrankable" issues with this map. Fixing these early will make the modding process (and my ability to mod) go much smoother.

03:46:127 - There should be a red timing section here, to reset the measure and properly align the downbeats. You might want to also go through and readdress your NC job after this; it seems like a lot of NCs were placed with the downbeats in mind, though since your downbeats are wrong your whole NC job seems wrong.
There are some pretty major tonality issues in both the Koigokoro and Daidai sections:
01:39:693 (1,2,3,4,5,6,7,8) - These jumps seem overdone for the map as is. Compared to 00:56:836 (1,2,3,4,5,6,7,8) - , they are much more intense, but these parts of the music are the same in tone. Same for 01:53:407 (1,2,3,4,1,2,3,4) - , etc. If you are going to use jumps this large, you should make the first kiai consistent with this. This is unrankable otherwise, QAT doesn't like difficulty spikes.
And as for the Daidai part, well...
03:32:794 (1,2,3,1,2,3,1,2,3,1,2,3) - This part of the song is slow, slower than the entirety of Koigokoro, but these jumps are as large as Koigokoro's kiai. I realize Daidai's BPM is lower, so jumps need to be larger to be considered as jumps. But this just seems really overdone, as do all similar slow parts of Daidai.
The kiai section has a key change. Usually this means everything will be made more intense compared to previous verses. I'm not sure if you took this into consideration, maybe I'm just imagining things, but it looks to me like the jumps in the kiai are the same as the jumps in the previous chorus. You may want to consider switching things around so the jumps in the kiai are larger than the rest of the Daidai section.
Oh, and I guess this is a good place to point out that you should add some combo colours :V
