00:51:744 (1,2,1) - This plays so awkward. I tried all kinds of things to fix it but I really can't think of much to suggest. Basically the inconsistency of this with 01:01:494 (3,1,2) bothers me, especially because the latter reads so well.
I guess what I can suggest for that is to move (2,1) to be stacked underneath the tail of 00:51:744 (1), but honestly I don't think that suggestion improves it much.
01:40:644 (1,2,3,4,1,2,3,4,1,2,3,4,1,2,3,4) - You should either end these on yellow ticks or make 01:45:444 (1) and 01:46:044 (1) end on blue ticks for consistency.
01:46:644 (1,2,3,4) - Honestly I think these would be better off half-speed but if you decide you want to keep these 1/8 you can end them on yellow ticks. Or at least make their endings match with the sliders I mentioned in the point above.
01:47:844 (1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8,1) - This is why I suggest your buzzsliders stick to 1/4. Because the sounds are "slowing down." Also, I think a proper accelerator stream might fit a bit better (instead of 1x to 1.8x have the spacing increase gradually).
02:05:469 (2) - Consider removing this circle. The slider moving into it is a quarter note and a half, so the readability (in terms of timing) for (2,3) is quite awkward.
02:06:444 (1,2,3) - A missing note on the red tick is bound to have people mistiming (3) and while that's okay in scorev1, in scorev2 that makes this nearly impossible to play properly. Consider moving (3) in closer and putting it on the red tick maybe?
Note that I mention scorev2 not because I care about this map being played competitively, but I think the slider should be on the rhythm and this syncopates (and thus ignores) the red and white ticks which I think are very important in this specific measure of the music.
02:10:644 (1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8) - Also consider changing this to a proper accelerator stream, in order to highlight the importance of technical skill here.
02:12:744 (2) - I don't understand why this is so far away from the previous sliders, and it also makes 02:13:644 (1,2) seem really out of place because there's very little hint as to when they come in. I'd suggest changing the spacing of 02:11:844 (1,2,1,2,1,1,2) so that either it is consistent (i.e. constantly increasing or just constant).
02:24:294 (3,4,1) - Consider unstacking (3,4) to be consistent with the rest of the section.
02:26:694 (3,4,1) - Blanket meme. Really I'm just mentioning it to support why I suggest you to fix the (3,4) I just mentioned.
02:32:244 (1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8) - I know you want this stream to be interesting but really it plays awfully. Maybe join them, maybe make their spacings the same, maybe make the curve of the first one less than 180 degrees, maybe make the second one properly blanket (8) of the first stream, there are many ways to fix this but honestly I feel like it plays wayyy too weird.
02:37:044 (1) - I think this would play better as a kickslider facing into (2).
02:37:194 (2) - Oops? I think you want to put (3,4,5,6,7,1) a bit down and rotated clockwise like 15 degrees?
02:44:244 (1,2,1,2) - Fix this angle to be a proper multiple of 30 degrees.
02:45:144 (3,1) - I feel like these would make much more sense if they ended on red ticks.
02:46:794 (2,3,1,2,3,4,1) - I see what you're going for but this is hella awkward to play especially considering how many 5-note streams you put earlier, consider making this a bit more uniform for example by uniting this into a single circular stream.
02:51:894 (1,2,3,4,5) - Why not make all these equally spaced if they're part of the same combo?
03:22:644 (1,2,3,4,1,2,3,4) - Make these angles a bit nicer, by making (1,2,3,4) form a symmetrical trapezoid along a line passing through the points halfway between (1) and (3) and halfway between (2) and (4). Alternatively, you could be boring and just make it a rhombus or square with z-shape jumps.
03:55:044 (1,2,3,4,5,6,1,2,1,2,3,4,5,6,1,2,1,2,3,4,5,6,1,2) - If you really want to be edgy, I feel like this section could be more enjoyable by making all these into kicksliders that point away from the next note. Just because we came out of two jump sections.
04:14:319 (2,3,4,1,2,3,4) - I feel like this is a bit too difficult to read because the sliders have intense counterflow. You might be able to reverse the directions of some of these sliders to fix this.
04:19:044 (1,2,3,4) - Same here.
04:27:294 (1,2,1) - Either stack (1,2) to have the slider blanket them, or just make (2) evenly spaced between (1) and the slider.
04:33:444 (1) - You should be ashamed of this.
I'd suggest using probox's tips on slider art to make this slider look a bit more pretty. Especially since you have such a "mechanical" feel with all the "proper" sliders in this map, this one feels just so out of place.
04:44:244 (1) - Move this a tad to keep the spacing consistent with the stream that leads into this one.
04:49:494 (3,4,5) - Make it into a proper equilateral triangle pls.
04:52:644 (1) - Maybe move this to blanket (3) of the previous pattern?
05:01:044 (1,2,1,2,1,2,1,2) - Again, this would play much better shaped like a proper symmetrical trapezoid.
05:05:844 (1,1,2,1,2) - I get what you were going for, but I don't think it plays nicely. You could keep the idea and fix the readability if you made the circles slant down and to the left so that at least the last circle is touching the head of the last slider.
05:14:244 (1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8) - It doesn't make too much sense when all throughout the map you have accelerator streams for buildups like this and here the spacing doesn't increase a lot. Make it consistent with the rest of the map.
05:22:794 (3) - Fix this slider so that the first and second red points have the same angles and distances to slider ends.
05:23:844 (1) - Again, I don't like this slider, it looks relatively ugly when the rest of your sliders are very "mathematical" and stuff. It's okay because of (2) underneath the end but you can probably make this one look at least a little better.
05:31:344 (1,2,3,4,1,2,3,4,1,2,3,4,1,1,2,3,4,1,2,3,4,1,2,3,4,1,2,3,4,5,1,2,3,4,5) - I'd suggest keeping these consistent. Use those cool "hold" sliders or the straight ones, but mixing it up here makes it feel like you were running out of ideas to make it interesting. Sometimes it's not about keeping it interesting, but keeping it fun while still being consistent.
05:53:844 (6) - This circle doesn't need to be there.
