Regarding the kiai of Qingyi diff being different each other, at least they are commonly fast in sv which creates a difficulty with non-kiai sections. The major difference I can see is the slider styles, and I think the map can work as the current design (although I'm not really a fan of this because basically the song is similar, and the expression was different but I respect your interpretation).
However the rhythm selection of 01:46:568 (1,2) - 01:48:068 (1,2) - 02:10:568 (1,2) - 02:12:068 (1,2) - vs 03:45:068 (1,2) - 03:46:568 (1,2) - 04:09:068 (1,2) - 04:10:568 (1,2) - was way beyond different while the song being similar themselves. Even two kiai sections were having a different concept, applying a completely different rhythm / slider shape / sv concept here felt too much. At least assuring some minor consistency between these ones would be one thing I'd like to see.
And maybe you can consider making the break section of both difficulties consistently.
