General:
Add some tags? I don't know who is the vocal but add that character in tags? (Like if it was Elsie's seiyuu, add Elsie to tags etc etc)
Start your kiai at 01:10:327, 02:22:327, 03:10:327 ? It's on a downbeat and I feel like kiai starting there feels more logical.
Your NCing patterns are kinda random at chorus. Try to make sure they match. I'm not good at NC mods though so I'll point out some basics.
Normal:
00:01:139 (3) - Shorten this slider by 1/2? It sounds odd to me since the slider ends between two words. Making the slider end on one vocal sounds better.
00:10:327 (1) - Spinner might be short for beginners. Maybe extending it to the next white tick would be better.
00:36:577 (4) - Make your slider the other way so it won't touch the next slider.
http://osu.ppy.sh/ss/16622300:56:639 (4,5,6,1) - These overlaps are not pretty ;_; Perhaps you could rearrange this pattern to make it look more visually appealing?
01:24:014 (4) - NC here for consistency with your previous pattern at 01:12:014 (1) -
01:30:952 (5) - Space this? You've been stacking 1/2s a lot so stacking a 1/1 would confuse beginners.
01:37:327 (1,3) - The slider blankets could be made better, I could make it if you want.
01:40:327 (1) - The overlap with 3 is kinda annoying. Perhaps move this slider somewhere else?
01:50:827 (3) - Move the second to the last point one grid right.
01:54:952 (1) - Space these? You've been stacking 1/2s and stacking 1/1 now would confuse beginners.
02:02:077 (1) -
Overlap. Maybe make a different slider? Or make it face somewhere else?
02:08:639 (6) - NC for new verse?
02:28:327 (2) - NC because you NC'd at 02:40:327? It may be only one slider but it's because you're mapping it so differently for the both of the chorus.
02:31:327 (6) - This slider doesn't blanket 5 too well, perhaps remake this slider?
03:16:327 (3) - NC here to keep it consistent at and 02:28:327 02:40:327?
03:25:327 (3) - The blanket could be better. Use approach circle as a guide.
http://osu.ppy.sh/ss/166226Hard:
00:03:014 (1,2,3,4,5,6,7) - I think it might be too hard for hard o.o Since like you stacked some and then you didn't stack some. Maybe just space them out?
00:10:327 (1) - Extend till big white tick?
00:44:077 (10) - Space this? Seems rather flow breaking to wait for the time to hit the next note when we could be moving D:
00:55:327 (1) - Make it like this instead?
http://osu.ppy.sh/ss/166229 It feels awkward to move your cursor back after the last repeat, but making it like the picture makes you move smoothly after the repeat.
01:12:577 (3,4,5,6,7) - This pattern might be too hard for hard since it might be hard to know how long this back and forth combo is. Perhaps some different pattern would be better?
01:13:889 (8) - The overlap looks weird here.
01:18:577 (1,2,3,4,5) - Same note about back and forth notes.
01:31:327 (3) - Perhaps use .75x slowdown? You were doing 1x during the whole chorus and tell it switches to .5x all of a sudden.
02:10:889 (2,5) - This doesn't look too nice orz
02:14:827 (4) - Ctrl+H and space? It looked confusing since I thought there was only one repeat cause you stacked it. If you do, space it, you also get rid of the overlap at 02:15:577 (6)
02:24:014 (8) - NC should be at this spot, but it's a slider end. Maybe add two notes and NC at 02:24:014?
02:36:014 (6) - Same note. NC should be right here, but slider ends here. Maybe add two notes?
03:12:014 (7) - ^
03:21:764 (1) - I think this note may be too fast after a spinner. Perhaps shorten the spinner by 1/2?
03:24:014 (7) - Same note as 02:24:014 (8)
03:32:264 (7) - Please don't put a note under slider. It's very confusing sometimes. Please move this note somewhere else.
03:36:014 (7) - Same note as 02:24:014 (8)
03:50:639 (6) - Here.
136,240,230639,6,0,B|316:268|388:144|256:-8|124:144|196:268|376:240,1,520
Neptunious:
00:10:327 (1) - Extend till big white tick?
01:31:327 (5) - Change it to .75x? Change won't be as drastic and unpredictable imo.
01:43:702 (1,1) - I don't think you need these NCs at all. Remove it?
Nothing much to say.
Overall:
I think you should try to avoid overlaps orz. I didn't mention it in Neptunious since I don't know if it was intentional. It's just my opinion. I kinda like maps better if they don't bad overlaps.
