Hello.
Insane1.
One flaw that I identified immediately after skimming the map is that the difference in pace of gameplay between the slow and the fast parts of the song is highly similar, which you ought to amend to reflect the objective sensations the artist intends to give. Such an amendment would perfect the organisation as well as diversify the individual segments which will improve the overall quality of the map. Examples of the problem are:
(a) 00:00:700 to 00:08:783, the spacing and the slider velocity ought to be significantly lower and slower respectively than the other parts in the rest of the map due to it being the most tranquil segment of the song. Whilst you do a good job in the latter, improvements can be made in the former, 00:01:633 (2,3,4), 00:02:876 (2,3,4), 00:04:275 (2,3,1), for instance, are equally distant as, if not of bigger spacing than, patterns in the relatively fast parts, such as 00:10:338 (2,3), 00:11:581 (2,3) and 00:12:825 (2,3).
(b) 00:10:027 to 00:14:923, the spacing in this particular segment is obviously meant to be faster than the previous one and thus, notably bigger spacing and faster slider velocity are recommended.
(c) 00:15:001 to 00:32:410, the speed of this segment is between the mentioned parts, and the spacing, therefore, should be smaller than the slow part but no more massive than the fast part.
For if you applied the modifications above, please also make the same applications on other parts. Reiterating that the segments throughout the map appear to be homogenous, and applying what said above would greatly improve the quality of the map by diversifying individual parts.

As for ornamental value, unintended overlappings that occasionally appear in the map deteriorate the aesthetic of the patterns/flows that are temporarily near the overlappings. To illustrate, 00:17:022, 00:17:488 (1,2), 00:55:415 (1,1), 01:00:856 (1,3) , 01:07:540 (2,6) and 01:23:705 (2,4) are examples of which I believe are unintended but consequences of perhaps, distance snap or a lack of idea of how to position them. They, subjectively speaking, are fairly messy and purport to have no relations whatsoever to each other. Demonstrations on how to fix them are thus:
(a) 00:16:866 (3,5) :
(b) 00:55:415 (1,1) :
(c) 01:00:856 (1,3) :

Frankly speaking, I see no creativity in the entire map. From a mapper's perspective, speciality is particularly desirable and is a major factor in determining the quality of a map. A repeated melody is often where mappers put their unique patterns on, as a result, the pattern will be on the stage for multiple times that get the players' attention. In the case of this map, 00:55:415 to 00:55:882 is the most repeated melody, not only does it appear in the slow part (00:00:700), but also several times in the kiai time and other parts of the map. Try to think of a pattern which you consider as eye-catching, and put it in the slow part in slow speed, in the fast part, fast pace. Indeed, if you could, so creatively, invent more than one creative pattern, that would massively boost the quality of the map.
