Change your OD and HP values for the Kantan to 2, Futsuu to 3, and Muzukashii to 4. Another option is changing the OD and HP values for the Kantan to 3 and Futsuu to 4 and keep everything else.
KantanSuggestions:
00:22:829 (20) - Change to
k.
00:28:763 (24) - Remove finisher.
00:32:884 - There can be a slider here until 00:34:697. Remove the spinner there.
00:42:609 (9) - Change to
d.
01:04:367 (11) - Change to
k and put a finisher. Changing the colour is optional.
01:16:235 (24) - Remove finisher.
02:19:532 (22,23) - Switch colours for each hit.
Optional:
I thought this difficulty was a bit too easy for a Kantan (I guess there are easier ones though). You have many sliders in this map that match the music. If this was standard, that'd be just fine, but because it's Taiko, maybe replace each hit of the slider into actual
d's or
k's. For example, you can change 00:05:027 (2), a slider, into
dkd. You can choose whatever colour sounds best to you. The only exceptions for this are: 00:19:532 (17), 00:20:521 (19), 01:07:334 (14)
00:18:873 (15,16) - Remove finishers, if you want to.
01:15:081 (22) - Remove this hit if you're going to replace the sliders with hits.
FutsuuSuggestions:
00:32:884 - There can be a slider here, like in the Kantan. Remove the spinner again.
00:36:675 - There's a bit too much time between hit 3 and 4. Maybe add two
d's at 00:37:334 and 00:37:664.
01:16:235 (50) - Remove finisher.
01:20:521 (58,59,60,61,62, 63, 64, 65) - Rather than this rhythm, I'd move hit 59 to 01:20:851, hit 62 to 01:21:840 and hit 65 to 01:22:829. Change colours if you need to. This matches the instrumentals more.
02:15:576 - The second kiai time is way to easy compared to the rest of the song. Add hits.
Optional:
Similar to the Kantan, there are spots where you can replace the sliders with hits. The exceptions are the same as the Kantan. I'd recommend doing this especially in the Futsuu because it'll make it sound better, without making it too hard.
00:18:873 (37,38) - Remove finishers, if you want to.
MuzukashiiSuggestions:
00:20:521 (78) - This hit could be a
ddd triplet.
00:22:994 (90) - Remove hit.
00:27:444 (114,115,116) - Remove hits 115 and 116, and change hit 114 to
k.
00:52:334 - Add a
d here.
00:55:961 - Same Thing.
01:23:488 - Add a
k, then every 1/2 beat, add a
d. Should look like k d d d k(hit 350)
01:16:235 (329) - Remove finisher.
01:24:147 - Lower the audio volume for this section.
01:41:455 - Add a
d.
Optional:
01:24:147 (350) - I wonder why you didn't keep this part a rest time?
OniSuggestions:
00:16:400 - Add a hit, your choice of colour.
00:16:730 - Same Thing.
00:22:417 - Add a
d. Not a 100% sure about this one, so ignore if you don't think its right.
00:29:587 - Add a
k.
00:46:895 - Same thing.
00:47:059 - Add a
d. Add another one a 1/4 beat later to connect with the stream.
01:09:642 - Add a
k.
01:09:807 - Same Thing.
01:09:972 (469) - Change to
d.
01:11:125 (473,474) - Change to
k.
01:19:038 (513,514) - Same Thing.
01:21:016 - Add a
d.
01:24:147 - Lower the audio volume for this section.
01:57:774 (731,732,733,734,735,736,737,738,739,740,741,742,743) - Change this stream. I would map it starting from 01:57:774, dkddkddkddkdk. This will also probably affect the difficulty rating.
Optional:
01:24:147 (548) - Again, I wonder why this isn't a rest period?
01:31:318 (568) - This hit is questionable. Remove if you want to.
01:41:950 (616,617,618) - Go in 1/6 beat snap divisor, and snap hit 617 to 01:42:059. Add a
d at 01:42:005. This is similar to the rhythm of the instrumentals, but it significantly raises the difficulty rating all the way to 4.99 stars. Your choice.
02:35:274 - Add a
d. Change 02:35:191 (1035) to
d.
This song is great. It reminds me of a lively historic town. The background fits perfectly. Good luck on rank!
