Easy-Note that most of these suggestions about the sliders were made under the assumption that you used curved sliders for sliders without ticks in them, and that when you used a linear slider, you made sure it had a bump or angle switch where the tick is. I also made the assumption that you used curved sliders when you needed to flow with a harsh angle, instead of using linear sliders.
-01:22:810 (3) - This slider should probably be curved because it would then fit your choice of making all sliders without ticks in them be curved. Even if it is at the top of the screen, you could make it curve downwards. This applies to 02:31:930 (3) - as well, but that one fits the section better since you seem to use a lot of linear sliders in that section between the kiais. This also applies to 03:26:650 (3) - and that one doesn't fit the section since the other sliders without ticks in them are all curved
-02:49:210 (1) - I think that this note should be stacked under the slider end, like how the other notes were stacked before it
-03:14:650 (4) - This slider should have a bump in its path, like most other linear sliders in the song. This applies to 03:31:930 (2) - as well.
-03:28:090 (2) - This slider doesn't match the other linear sliders, most of the other ones use red anchors solely, while this one has 2 whites and 1 red. I dont see anything such as vocals to fit this pattern so maybe it would be best to make it fit the rest
A bit nit-picky, but I find it hard to mess up an easy difficulty so I'm being really attentive.
Normal-It seems that many of your sliders aren't matched up linearly perfectly. This seems to be done on purpose, although it does make the map a bit irregular. You may have done this because you wanted to make it less linear of a flow, but since there is slider leniency, it doesn't really matter and could be considered to look worse.
-01:17:050 (1) - I don't think this slider needs to become irregular like that, there is the kiai emphasis, but you don't repeat this on the other kiai starts. If you did this sort of slider on other kiai starts, it could make map more interesting, but as it stands, this slider is kinda weird.
-02:34:810 (2) - This note. It could probably be moved somewhere else to make the spacing easier to read because the slider after this note is further away on the timeline than most other notes, but it is stacked so it could be a bit misleading.
-03:12:250 (1) - You put the sharp curve on this slider because of the vocals, but there are at least two other sliders before this one that you could also do the same to. For example, 03:08:410 (1,4) - could also have the same effect applied to them.
Seems pretty good, but your like i mentioned before, the sliders are a bit irregular in terms of positioning so you should keep tha tin mind.
Hard-What is with that title. What. Also, your use of irregular sliders is irregular. You seem to be using them to accentuate the vocals, but you aren't using them often enough to be consistent
-00:24:250 (4) - This note is spaced too far from the slider. Other notes with the same beat pattern don't have this jump, why should this one?
-00:42:010 (6) - This one is a bit subjective. I don't think I chose the first case in which this occurred, but your triples are spaced closer together than your sliders that follow right after each other, even though the beats follow a similar pattern. You could either move the slider patterns closer together, or move them further away so that they maintain the slider velocity flow and are more different from the triple patterns. I mention this because you sometimes have triples, triples into sliders, sliders that last onto the red and then follow onto another slider, or sliders with a note between them. These all add rhythm by using a blue tick, but they are a bit inconsistent. Maybe I'm just being stupid and you can ignore this me for this one.
Nice map
