I'm a sucker for these DDR super-happy songs.
[Easy]Slider speed slightly too fast for easy, maybe?
00:33:033 (3) - Personally I'd put another one or two handles on this and make it a bit curvier.
01:01:158 (2) - Left a little bit maybe?
02:02:283 (1,4) - Might want to make these symmetrical.
02:05:283 (1,4) - ^
02:12:783 (2) - Might want to bring the end of this up a bit.
02:21:783 (5,1,2) - Spacing is inconsistent here. Personally I'd move (1) and slider [02:24:783 (4)] right a bit.
02:28:533 (2), 02:30:783 (1) - Are these meant to be symmetrical?
[ouran's Normal]00:15:783 (4) - One right to line it up with slider (1) of the same combo?
00:27:033 (4,5) - This might sound nice if you remove the whistle from the start and end of the slider (leave the one on the bounce), add a finish to the end of the slider, and add a whistle to (5).
00:30:033 (4,5) - ^
00:34:533 (1) - Finish overkill! D:
00:43:533 (1,2,1,2,3,4) - Might want some hitsounds here.
00:52:908 (2) - Down and right one.
00:58:908 (6) - One left.
01:07:533 (1,2,3,4) - Inconsistent spacing here. It plays as if (3) was on a red tick, so you might want to make the sliders more of an M shape.
01:10:533 (1,2) - Again, finish overkill! D:
01:21:033 (2,3) - Same here as with 01:07:533 (1,2,3,4)
01:26:095 (2) - This feels too long. I think you should end it on the previous red tick (01:26:470).
01:29:095 (2) - ^
01:34:533 (1) - Finishes! D:
02:08:283 (1,2) - Make these parallel.
[Insane]00:14:658 (4) - Up a bit to line it up with (2) and to be in the middle of the sliders. Might want to move [00:15:408 (6)] up with it. Something like [01:17:658 (4,6)] would look great.
00:32:658 (3,4,1) - This spacing is evil! D:
00:34:533 (3,4,5) - This plays really weird. :/
00:39:033 (1) - Right a bit?
00:54:970 (6) - This note feels overmapped.
01:08:095 (2,3,4,5,6,7,8,1,2,3,4,5,6,7) - The sound of silence.... >_>
01:34:533 (3,4,5) - Same as [00:34:533 (3,4,5)]
01:57:783 (4) - Up and left one?
02:08:845 (2,3,4,5,6,7,8,1,2,3,4,5,6,7) - So quiet... <_<
02:27:033 (9) - Maybe get rid of the finish on the end of this slider and move it to [02:27:783 (1)] instead.
Nice! <3
