I'm fine with most of it but I still don't think 04:57:138 (1,2,1,2) - should be NC'd (call me petty yes) and here's why:well that sound fair, but i still think keeping at least the first nc 04:57:138 (1) - is needed
For most of the map the only emphasis you ever use in vocal jumps in the kiais is 1>2 NC'ing and increased spacing. When you do this at the end of the map here you remove one of those tools to emphasize the final vocals that start at 04:57:865. Because the previous notes were already 1>2 you can't use the NCing to show a change, thus the emphasis is actually weaker than in other parts of the map like 03:02:228 (1,2,1,2). Come to think of it isn't 01:46:592 (4,5,6) - supposed to be all circles? And if it isn't, this is a good example of how your NCing can provide some emphasis for the increase in intensity on the downbeat.
I'm not saying it's bad to have them 1>2 before the downbeat, but you don't make use of many flow changes so the emphasis gets very lost when you NC before a major song change. That coupled with 04:56:228 (2,1,2,3) - not being normally NC'd ruins the NC patterning imo.
That's my two cents, but I feel it would definitely benefit the map to keep the NCing for the downbeat instead of before it.
and yea 01:46:592 (4,5,6) - should be better as circle you're right
