Hello! Modding for M4M.
[General]
00:00:888 - The silence here in the beginning is really unnecessary. Consider editing it out.
[Normal]
00:34:102 (1) - This is a bothersome overlap. I'd personally take a hit to spacing consistency here to move (1) over so that it isn't touching (2). Because of your large CS, a slight increase in spacing here won't affect play at all, and it'll look nicer, which is really important on slower difficulties.
00:40:888 (4,1) - Don't let these overlap. Keep the true spacing (not the snapping) between (4,1) the same as between (3,4). Personally I wouldn't let anything overlap in this section, or at least increase the overlap so they aren't just barely overlapping, but that''d be quite a big change to make.
01:14:995 (2) - aaaaa. I know you're trying to follow the bass drum rhythm here but these sorts of polarity changes are really dangerous on lower difficulties unless properly mediated by a slider. I'd move this back to 01:14:817 or change this section so that the player slides into it.
01:26:602 (3,1) - Keep the true spacing here consistent with 01:25:531 (1,2,3) will look nicer.
01:34:102 (2,1) - Bothersome overlap.
02:09:102 (3,2) - ^
02:11:602 (3,1) - This one isn't as awkward-looking but if you're going to fix the above make sure to fix this one too for consistency.
In general, I think if you fix these overlap issues it'll also make it easier for players to identify polarity changes (and thus smooth up play), such as at 02:17:674 (3,1). If your only overlap occurs on 1/2 beat timings then players can recognize those tricky areas more readily.
03:26:959 (1,2) - Unnecessary overlap.
04:08:388 (1,2) - ^
03:30:174 (2,1) - Adjust the blanketing here.
03:42:317 (2,3) - ^
05:14:102 (2,3,4) - I'd try and make the note curvature here more consistent. The angle at (2,3,4) is a bit too acute in my opinion.
This is a very well-crafted Normal! I really like your slider shapes and your overall arrangement, and the rhythm you've chosen for the kiai sections is enjoyable to play through. Because your map is so beautiful to look at, I've focused on the small visual details here.

Drain Rate: consider decreasing. You've got some lengthy slow sections in your map, and with the current DR it's impossible to recover HP at those sections.
01:31:959 (1) - The spacing on this one is somewhat extreme. The rest of this section uses 0.9-1.2, but here you've got 1.6 suddenly. This wouldn't be a problem if you had more jumps around here like this, but you don't, so it's just out of place and unexpected.
03:36:245 (3,4) - Switching these two in time improves the flow here.
03:39:459 (4) - Somewhat awkward. Maybe try this instead?
ctrl+g, move down, rotate CCW.
03:40:531 (7) - ctrl+g. This improves the flow in my opinion. Move the 6-slider a bit further out if you decide to do so. This will also get rid of the sort of bothersome-looking overlap that you have here.
03:40:888 (8) - ctrl+g this if you did the above.
03:43:388 (3) - Awkward flow. This is your biggest jump in the section by far (2.73x), and unfortunately slider leniency doesn't help much here. I'd recommend to ctrl+g this, and then move it down a bit, with some rotation for symmetry. You might have to adjust the positioning of the next stream a bit to compensate this change.
03:47:674 (3,4) - Swap these two in time; this flows better for me.
03:57:495 (5,6,7,8,1) - Watch the spacing here. Because of how (5,6,7) are spaced, (7,8,1) looks very much like a 1/4 triple. Especially since you've got this here: 04:01:067 (5,6,1)
04:03:567 (8,9,10,1) - Same issue, the previous 04:01:067 (5,6,1) makes the spacing for this deceiving. Why not use the same spacing that you have here? 04:05:531 (1,2,3,4,5,6,7,8)
04:08:834 (6) - Owwwww. This stream in general actually could use some cleaning up. Using "Convert slider to stream..." with a single huge slider might help, though it'll be pretty annoying to make that slider, haha...
04:14:281 (1,2,3,4,5,6,7,8,9,10,11,12,13,14,1) - Awkward curvature. I'd recommend making this perfectly circular, or doing a wave shape. Or even a straight line would look better than what you have now.
04:35:352 (4,1,2) - You use 0.7x here for these notes that are 1/2 beat apart, and this makes your spacing at 04:39:459 (1,2,3) appear somewhat inconsistent. I'd recommend to choose one spacing for these. You've got enough spacing acceleration later on, so making these consistent with each other wouldn't hurt, in my opinion.
04:54:459 (1) - Consider ctrl+g. You'll have to make a CW rotation to improve flow if you do so.
04:56:245 (3) - Curve this the other way. This will provide a much better landing from the 2-slider.

Overall, this is a great mapset! Your arrangement and patterns are nice in general. Good luck with ranking!
