00:17:455 (10,11,12) - For some reason I find this pattern a bit odd-sounding (by that I mean your pattern ends up being how you want, but it ends up being a bit unnatural) - and your patterns past the 5 note sequence ends up being differently placed and more natural. I don't know what you would think of this:
http://i.chiyozel.com/epnSVcz2 since it's not exactly what you want but gives a smoother transition.
00:31:091 (28,30,32) - Make them as dons, as all your kats were mapped to snares earlier. Here, you've got only kicks, and you've mapped'em as dons before. And following the song as there's nothing between your kicks.
01:29:728 (113,114,115) - 01:34:091 (120,121,122) - 01:38:455 (127,128,129) - They play weird, as there's no real thing behind them (especially 120-122 where there's nothing at all), maybe keep these simple. Same goes for the second Kiai time.
01:44:728 (137,138,139,140,141,142,143,144,145,146,147,148,149,150,151,152,153,154,155,156,157,158,159) - This pattern although accurate, should be less dense due to the 3/4 patterns. Some people may not get these. I'd something like this at most :

00:21:273 (17,18,19,20) - This gap has shocked me a bit, however if you add a note here you'll make the pattern very long. I have found a compromise, I don't know how you think it is, is to move 00:21:273 (17) - to 00:22:364 - . Of course you will have to change it to k to fit your dkdkdk pattern.
00:40:910 (54,55,56,57,58) - Have you inverted colors on purpose ? If not, invert these three: 00:41:455 (56,57,58) -
00:43:091 (59,60) - Add a note between those two ?
01:05:728 (98,99,100,101,102) - I'd rather see this:
http://i.chiyozel.com/eK2hqV1O - This way you'll keep the kicks in the chart and doesn't feel awkward to play.
01:31:091 - , 01:39:819 - add a d there as well, so you get the snares mapped ? Same goes for the second Kiai time.
01:48:137 (187,188) - 01:52:501 (196,197) - These two doublets were hell surprising to me due to an odd timing (both blue ticks) and may lead to people wondering what these were mapped to (seems to be a sax or something of the sort which isn't predictable).
02:02:196 - This verse seems to be much less dense than the first one, maybe add some more notes so you make them consistent rhythm-wise (but your colors may be different for variety)

I really loved this map to be honest however some of the rhythms felt off a bit (you put 1/6 snapping in parts where 1/4 is dominant), for example:
00:17:455 (21) - to 00:26:182 (66) - there's no real 1/6 in this, you can put 1/6 rhythms like 00:21:546 (41,42,43,44) - but don't make 1/6 dominant in 1/4 parts! (might be wrong, I heard the lyrics were closer to 1/4 than to 1/6.)
Other than that, very sick map. I really like mixed 1/4 and 1/6 when the songs asks for it (Barbra Streisand sup?).

For this diff, since you've started to put more complex patterns, I think putting 1.6 as SV should be more judicious.
00:46:364 (109,110,111,112,113,114,115,116,117,118,119,120,121,122,123,124,125,126) - Cut this pattern a little bit so it doesn't feel a bit too long ? This lasts for 4 secs without real break.
I think this diff is polished enough as well, but I think my biggest worries are how you used 1/4 and the 1/3 + 1/4 patterns which could confuse and also make that diff close to Oni.
