I barely know any musical terms, so forgive me for trying to explain it with horrible english~ Just throwing in my 2 cents.
Prestissimo
00:00:209 (2,3,4,1,2,3,1,2,3,1,2,3) - I understand what you are trying to do here, except it plays really awkward as it is now. I think it would be better as one long stream where you will emphasize the change in music, like you did now with a new combo/slider jump, except with a decreasing spacing. Let's say you start with 1.0x spacing, and then make it feel decrescendo by decreasing the spacing by 0.1x or 0.2x for every 5th note (red tick) in the stream.
00:02:695 (1,2) - Again, playability. Maybe connect the notes as a speed up slider, to still emphasize note (2)? As it is now, it just plays down right bad.
00:05:695 (1,2,3,1,2,3,1,2,3,1,2,3,1,2,3,1,2,3,1,2,3,4,5,6,7) - Here you did do a spacement decreasement, except the slider jumps completely take over from that effect, which is a shame. The slider jumps take away the entire decrescendo effect, because jumps feel crescendo. There's no music indication for a jump. There is indication for a change, but change which slows down. A jump marks a speed up, crescendo effect or forte / fortissimo part.
00:13:238 (1,2) - Plays, again, awkward, and there's absolutely no indication for there to be a slider.
00:20:609 (1,2,3,4,5,6,7,8,9,10,11,1) - Why is the slider here 1/4 later while at every part before it it's 1/4 earlier? Btw, it plays way better and sounds way better like this.
00:22:152 (1,2,3,4,5,6) - 1/4 doesn't really seem like the right idea here. I would just keep it 1/2.
00:45:295 (1,2,3,4,5) - Simply looks bad. It may follow the sheet, but it is not following with the map or the music. It doesn't ask for these kind of notes at all.
00:49:666 (4) - 00:50:009 (4) - 00:50:352 (4) - Why is the 'twitch' in the stream on the 4th note? Shouldn't it be on the 3th? Try stacking (3) and (4), it plays/looks okay. Not too fancy though.
00:50:780 (1,2) - Why the sudden big jumps? The music doesn't ask for these big jumps at all.
00:52:152 (1,2,3,1,2,3) - This is probably the only time I'm going to say this but... WHERE ARE THE JUMPS? If there's any part in the music which screams for jumps it's this part.
01:02:438 (3) - Make this a horizontal flip from (2).
01:02:780 (1) - Place this under (2) ^ also add a finish hitsound perhaps?
01:03:123 (2) - And this one under (3) ^ This way you'll get a back&forth jump.
01:04:238 (1,2,3,4,5,6,7,8,9,10,1,2,3,4,5,6,7,8,9,10,11,12,1,2,3,4,5,6,7,8,9,10,1,2,3,4,5,6,7,8,9,10,11,12,
1,2,3,4,5,6,7,8,9,10,1,2,3,4,5,6,7,8,9,10,11,12,1,2,3,4,5,6,7,8,9,10,1,2,3,4,5,6,7,8,9,10,11,12,
1,2,3,4,5,6,7,8,9,10,1,2,3,4,5,6,7,8,9,10,11,12,1) -
No. No sheet of paper with notes on it can excuse this tragedy.
01:18:038 (4,5) - Plays bad.
01:19:580 (3) - You should stack this under (1) and (2) and then maybe change the shape of it of course.
01:22:323 (3,4) - Why is this jump bigger than the one at 01:20:952 (3,4) ? You should make it like the first one.
01:27:123 (1) - Remove this note and a repeat on the slider before it. Looks, plays, and sounds more awesome.
01:32:095 (2,3,4,5,6,1) - Why is this all of the sudden a 5 note - slider stream when it was a 4 note - slider stream before? There's no indication for such change at all. And this makes it play extremely awkward because you end up on the 'wrong key', the key you don't single tap with. Yes, I did this in my guest diff for you death note map as well and I regret it big time. It plays and looks extremely awkward.
01:37:409 (1,2,3,4,5,6,7,8,9,10,1,2,3,4,5,6,7,8,9,10,1,2,3,4,1,2,3,4,1,2,3,4,1,2,3,4,1,2,3,4,1,2,3,4,5,6,7,8,9,10,1,2,3,4,5,

1,2,3,4,1,2,3,4,5,6,7,8,1,2,3,1,2,3,4,1,2,3) -
Again. No.
