General.
You forgot to reset your metronome at 00:36:733. Add a new redline there please.
Normal.
Use ar4 please. 5 is way too fast to be in the lowest difficulty.
00:41:298 (4,5) - Two circles feel a bit too difficult to be in the lowest diff. Mind making this to a 1/2 slider or something?
Not bad, but next time when making a "lowest" difficulty, keep some real difficulty aspects in mind. In this case, several 1/1 spacings are quite large while the bpm was high. Yet I feel I can consider this as the lowest one in this set.
Advanced.
ar7 at a map with nearly no jumps feels a bit high. At least, you'll want to balance the value after you've changed the ar of normal.
01:05:754 (2,3) - Even it isn't intended, the formation is pretty much like a blanket. You can improve it more.
01:09:994 - I think expressing the beat and the vocal at here would fit the song better.
01:20:754 (4,1) - There is a jump here, and I'm not really sure if the only jump of the map really deserves here.
Hard.
00:24:862 (4,5) - 00:26:818 (2,3) - Use 1.7x spacing for consistency.
01:26:216 (7) - Remove this object please. The song wasn't really strong to demand some object here. The only 1/4 click in this difficulty doesn't really seem to fit the overall consistency.
Light Insane.
00:30:568 (2) - The spacing suddenly decreased. It feels inconsistent while there wasn't some major difference in the song. Keep the 1.4x.
Insane.
Why is the diff name "insane" with a lowercase? It doesn't really make much sense with other diff names. Please use an uppercase.
Any special reason for using a different combo color with other diffs? Personally, the red color here felt a bit unfitting.
00:10:973 ~ 00:20:786 - I'd ask you a small rework on this section to reflect the intensity of the song better. Currently, the overall spacings here are pretty large which creates not much difference with other sections. That wasn't a nice map design, considering the music of this section was quite showing a difference. This part is weaker than other parts, and I hope you could reflect such aspect of the song. Structure issue.
00:14:560 (4) - Consider nc since the music seems to be a bit seperated here.
01:03:798 (1,2) - Starting the combo from (2) will fit the music better.
01:06:244 (1,2) - ^ Besides, you'll want to remove nc of 01:06:896 (1).
01:07:874 (5,1) - Considering other patterns such as 00:57:439 (1) - 01:18:309 (1) is starting the combo from the stream, I expect this to be consistent.
Ex.
What does the diff name mean?
The circle size is 5 along some big jumps which can lead to several miss. With that in mind, hp7 feels way too harsh.
00:00:702 (1,2) - No need for a manual stack.
00:14:397 (1,2) - Other spacings for 1/2 was 1.2x which didn't display a follow point. I don't really think this needs a small jump. This only feels like an inconsistency.
00:28:449 (1,2) - Is this 1/4 jump really necessary? This was the only usage in this section, and I think reserving this concept for further part would work more effectively.
00:50:754 (3,1) - 01:00:048 (2,1) - 01:11:624 (3,4) - I'd like to see more consistent concept here. The first one has a massive jump out of nowhere, which felt really sudden to be just once. And the final one wasn't even consistent in combo.
01:05:673 (2) - Can you consider removing this object? I can hear a beat existing in this part of the song, but the mapping concept didn't felt to be consistent with the overall idea in the kiai section. Such 1/4 jumps nearly appears right before when the kiai starts, and never appears except here. It look weak in structures imo.
It was nice to see the GD having a similar mapping concept with the host mapper's work.
