The spacing in that section doesn't make that much sense, currently it feels like you're increasing/decreasing the spacing with to real objective behind
Something you could do is by example, having a big spacing for the cymbals and a smaller spacing for the kick or having more variety in your rhythm so not only having a focus on cymbals + kick?
There's also the same problem with the last kiai (not entierely since the music differ a bit)
04:26:459 (1,2,1,2,1,2,1,2,3,4,1,2,1,2,1,2,1,2,1,2,1,2,1,2,1,2,3,4,5,6,1,2,1,2,1,2,1,2,1,2,1,2,1,2,3,4,1,2,1,2,1,2,1,2,1,2,1,2,1,2,1,2,3,4,5,6,1,2,1) -
I'm going to give you general advice instead of specific, as this map doesn't have many individual problems, but problems as a whole.
I'm directing this advice, yes, at the map, but you also want to keep in mind what I'm saying here for your next couple maps.
What's good about your map, and what you should continue to do in your future maps, is make recognizable patterns, and re-use them. Even from the very beginning, your patterns are very recognizable, such as 00:05:590 (1,2,3,4,5,6,7,1,2,3) - 01:10:807 (1,2,3,4,5,6) - and 01:14:285 (1,2,3,4). This is good. The map is very structured because of it.
There are two main issues with this map:
Starting with that second point, it's okay to re-use a pattern, but just switching up the placement, or the orientation of a pattern can help immensely. For example, at 00:16:025 - 00:28:198 - yes, the music does repeat itself, and you should still use a similar pattern, but I'd recommend you have the player move around the screen as you do so. Starting here at the top left at 00:16:025 - is fine. However, by the second time around, 00:19:503, I'd recommend maybe instead going to the bottom left. Little changes in where you put the pattern, what direction it's facing, etc. are good. It will stay a pattern, but it just adds a bit more variation.
About the first point, going back to this part - 00:16:025 - you want to work on the actual pattern itself placing more emphasis on the louder sounds. For example, 00:16:894 (1) - really doesn't have much emphasis, so it feels not that satisfying to hit. A way to fix this would be to move it down below 00:16:785 (5) (maybe around the coordinates x=259, y=259). This way, the player is strained trying to hit, emphasizing the sound. Now, you'd want to adjust the notes afterwards (00:17:220 (2,3,4,5,1)) to not be so far away, after you move 1.
Hope this helps! :)
