I'm going to leave my input on this, because this is a really good map and I'd like to see it ranked. There are only a couple flaws that I notice with this map, and I'm glad to point them out. =3
Normal
00:21:64 (2) - This feels uncomforatbly close to (1). This is easy enough to fix.
00:23:05 (3) - Same as before, a bit too close to (2).
00:25:86 (1) - Consider moving this a bit away from the previous slider.
00:27:26 (2) - Again, making a distance fix would be a good idea.
00:28:66 (3) - Repeat of above sliders.
00:32:87 (2) - Copy and paste.
00:34:28 (1) - Lemme make some photocopies of those same words.
00:38:49 (2) - Maybe move this a big back over. Might not be required, buuut...
00:39:89 (3) - See the above sliders. The distance matter for this would be easily remedied by moving (2) to the right just a little bit.
00:55:33 (2) - Are you getting all this down?
00:56:21 (3) - Imma broken record!!! XD
00:56:73 (1) - Yeah, repeats of the above sliders. Move a bit away from the previous sliders.
00:58:13 (1) - Copy/paste.
00:59:01 (1) - And again.
01:02:17 (1) - Bit away from the previous slider.
01:02:87 (2) - Same as above.
01:27:61 (1) - Distance check.
01:40:41 (4) - Something's bugging me about this one. Consider moving it a bit away again, I don't think it'd need much though.
01:42:34 (2) - Move this away a bit from the slider before. (consider how you have (5) of that same combo placed. Perfect example of how this should sit).
01:45:15 (1) - Away a bit from the previous beat.
01:50:76 (1) - Move away a bit from the slider.
01:54:10 (6) - Maybe move this a tough away from the beat before.
01:54:98 (1) - Copy and paste again. Also, shorten this by 1/4 beat and move it forward (->) 1/4 beat so it ends where it is now.
01:56:90 (2) - Little closer to (1). =3
02:01:29 (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22) - Freaking long combo. Consider possibly breaking this up a little.
02:09:01 (1) - Maaaaybe closer with the previous combo to keep the distance-time for this area of the map...
02:09:71 (2) - At the moment, there's nothing really wrong. Just make sure if you move the previous beat to double-check that you still have distance-time equality.
02:31:99 (1,2,3) - Funny enough, this part doesn't bug me, but still consider possibly making a tad more room between these sliders.
02:50:41 (3,4,5,6) - I don't have a huge issue with these, though I'll point something out like this on Hard later anyways. I'm going to tell you a little later that a certain group of beats on Hard feels uncomfortably close with each being a 1/2 beat apart and at only one grid width separation. This itself isn't as bad, though I feel you should still consider moving these beats apart a bit.
02:54:62 (3) - Consider moving this closer to the previous slider.
02:57:43 (1) - Move this away from the previous slider?
02:58:48 (3) - Tad closer to (2), perhaps.
03:01:64 (5,6,7) - Don't have a huge issue with this, but still put a little thought into whether you might want to spread these out a little bit for D-T equality.
03:03:04 (1,2,3,4) - More space, please.
03:17:25 (17,18,1) - Move these around a little... The spacing feels a little funny.
03:21:46 (3) - Maybe could use a bit more room from (2).
03:25:15 (2) - Might be good to make sure that (1) doesn't overlap this (makes you wanna feel like there's less time between the slider and beat than there really is).
03:28:66 (4) - Same as the previous beat.
03:32:87 (6,7,8,1) - Ok, let's see... Move (6) and (7) back (<-) 1/4 beat and rearrange to ensure D-T equality. It sounds a bit better this way.
03:42:34 (1) - Move a little away from the previous slider.
03:51:29 (5) - Make this 1/4 beat longer. Again, sounds a little better.
03:56:73 (10,11,12,1) - You might want to move these to avoid a change in the D-T ratio though I don't really have a problem with around here.
Phew... Didn't realize there were so many little spacing matters to point out. I'm not going to go through Hard or Insane right now, although I will come back to you on those ones. =3 In all honesty, I can't see ANY major timing issues. Everything noticable is just a spacing issue, and none that are even really big. I will check back after you update and I look forward to this getting ranked.
EDIT: Good morning~
Hard
00:14:10 (2,3) - Do you think you could realign these so that they're right under (1)? You can hold shift to turn off grid snap while you're placing them, or the other option is to put new beats in where there current ones are, while the slider is still visible. You can get them to snap right to the end of the slider.
00:20:24 (1) - Perhaps move this a little closer to the previous three beats.
00:21:64 (2,3) - Exact same thing as almost everything I pointed out in Normal. Put more space between (1) and (2), and (2) and (3).
00:39:89 (1) - Maybe a tad away from the previous slider. Just feels slightly uncomfortable, although this isn't a big issue. In fact, I think it might be a good thing to move this combo over just a touch, since then you're also putting a little less distance between this and the next combo, and I think that would be a good thing.
00:59:01 (3) - A bit away from (2), I would say.
01:39:01 (1) - These combos you have starting here.... Something just seems a little up with the timing, something which I'm having troubles with figuring out. Let's see what I can do, though.
----------
01:39:89 (4) - Move this back (<-) 1/8 beat.
01:41:29 (2) - Same as above.
01:42:69 (4) - Same as above.
01:44:10 (4) - And same as above.
01:45:50 (2) - Same.
01:46:91 (7) - Same. Also adjust placement around this area for D-T equality with (6) (maybe try a diagonal to your slider?).
----------
After that adjust spacing to account for the timing changes. I suggest turning off grid snap (or holding Shift) and moving over those beats you just changed the timing of and move them over so that they're about halfway between the notes before and after (with equal distance). Well, 01:41:20 (2) is a little different, as is 01:46:91 (7)... Still, I'm sure you can adjust these to have the right distances between them. If you're ever unsure, you can use the distance snap to place them, or even just as a guide to get an idea of the kind of space differences you need.
02:11:47 (4,5,6) - These feel a bit close to each other, I recommend moving these apart at least a little bit. Having them overlap gives the illusion that they're faster than other beats.
02:18:13 (1) - Move this back 1/4 beat and then adjust spacing between this and (2) for D-T equality.
02:25:41 (4) - Maaaybe a touch more space between here and (3). Doesn't have to be much. 1/2 of a grid width would do it. =3
02:26:38 (2) - Same as above, bit more space. I'd say a whole grid width would fix.
02:57:43 (1) - Maybe move this away from the previous slider.
03:02:25 (7,8) - I have issues with the 1/8 beat difference. It feels awkward. Move (8) 1/8 beat forward and then shorten it by 1/8 beat (make use of shift).
03:15:32 (3) - Same as the beats I covered above, move this back 1/8 beat and adjust distance.
03:18:13 (4) - Same.
03:19:53 (4) - Same.
03:20:94 (2) - Same.
03:22:34 (7) - And same.
03:31:11 (1,2,3,4) - Move all these back 1/4 beat.
03:33:57 (5) - Moving this down 1 grid width will fix any spacing issues here after fixing the previous beats.
03:39:53 (5,6,7,8,9,10,11,12,13,14,15,16,17,18,19) - I have issues with how this overlaps near the end, since I can't tell where the beats are. Please fix this.
03:49:53 (21) - A bit further from (20). Also, this current combo is pretty long, as is the previous, consider possibly cutting them into two combos each.
03:52:51 (4) - Overlap makes it look like it comes earlier. Adjust, please?
03:53:57 (1) - Between here and the previous slider, there's a decent bit of space. Fix around here for D-T equality as you fix the previous beat I pointed out. =3
Bah. I'll continue from there after school. Everything's lagging now so I can't do much. But I'll make sure to finish for Hard and all of Insane this afternoon.
