Got asked for opinion so here it is:
I think imma refrain from commenting on the first 1/3 of the map cuz I'm pretty biased against these types of LN usage.
The dubstep section, imo could use some more breaks. It is like these harsh dubstep songs that there is always a break in between each burst, so that no matter how harsh the sounds r, the listener (or in this case the player) can clearly distinguish which sound is which. Ik u tried to have these breaks represented by lowering the density of those sections down, but 1/4 still have stuffs going on. Rather than always having things noted down, I tend to find making the representation of the harsh sound harsher, and demand break where it really needs help both emphasizing the sounds and the breaks more.
For example, 04:23:365 (263365|3,263365|1,263395|2,263454|0,263512|3,263571|2) - the dubstep sound here could be harsher, and the vocal could be a bit more concise. Sth like https://osu.ppy.sh/ss/19532833/5930 could work, but that's the general idea.
Another one is at 07:04:530 where I think the lack of transition feels really jarring, and I can tell right away who mapped which section. This whole chorus part is a huge buildup, so I got a lot of whiplash when out of nowhere, the rice dump comes in - no hint from the previous section.
07:00:245, 07:39:102 suffer the same thing tho to a lesser degree, as the music here is getting quieter, but the density still stays at a very similar level. 07:51:673 could also use a buildup between alternating rice and LN and full LN too.
Overall, I think this is a solid map, tho as it is the nature of these types of map, I tend to find the lack of idea cohession to be a bit jarring. This is a pretty good base tho, gl with it <3
dubstep part OK, for 07:04:530 I think this is fine to keep as I think the pause with the rice notes 07:04:530 (424530|2,424530|1,424530|3) - show change in rhythm and something different is coming up. 07:00:245 and 07:39:102 may look like the same density but the overall patterns besides areas like 07:04:102 (424102|0,424173|0,424316|3,424388|3) - which are intended because of heavy kicks for 07:51:673 I somewhat agree but the difference of vocals between for example 07:41:388 and 07:42:530 are more noticeable then at 07:50:530 and 07:51:673 which is why the first part 07:50:530 has more longer 3/4 LN notes then at 07:51:673 - 07:50:530 (470530|3,470626|1,470775|3,470888|0,470959|2,471102|3,471388|1,471530|3) -
from 07:03:959 to 07:04:530 - would be great to replace some lns to represent the drums that refer to the same sound as 03:59:057 (239057|1,239057|2,239080|3,239150|2) just for a more challenging long note releasing
01:41:100 (101100|2,101100|0,101175|1,101212|0,101250|3) - vs 01:42:300 (102300|1,102300|0,102350|3,102375|0) - i wish the representation between the snares stayed consistent, by always switching up the snapping you create a feeling of chanciness throughout the entire section which degrades the quality and structure of the beatmap. just use some graced 1/8 since whatever you already have strays the closest to that.
01:57:600 - 02:19:200 - kill the bursts??? what are these trills
02:05:175 (125175|2,125200|1,125250|2,125300|3,125325|1,125450|2,125500|1,125550|2) -
02:09:450 (129450|0,129487|3,129487|2,129525|0,129525|1,129562|3,129600|2,129600|1) -
only 02:09:450 (129450|0,129487|3,129487|2,129525|0,129525|1,129562|3,129600|2,129600|1) type of trills for the sounds, cause 02:05:175 (125175|2,125200|1,125250|2,125300|3,125325|1,125450|2,125500|1,125550|2) represent the sound while keeping the difficulty still balanced
