Just a little suggestion, the whole map has 2 long handtrills (03:04:810 (184810|1,184810|2,184810|0) - and 05:18:557 (318557|0,318557|2,318557|1,318557|3) - ) and they all started from the left side. this has caused some players mindblock (like me), then they had to use Mirror mod for playing. I know these patterns are meant to follow the piano pitch, but I think doing so has already affected gameplay.
unfortunately, I must point out that this map's Timing point is wrong:
The time point is half a beat ahead of the correct position, which leads to rhythm misalignment in some positions, like the clap/snare sounds in the entire song is not on the beat line.
In this section (00:29:239 - 00:35:569 ), the drumbeat is also on the backbeat. If you pay a little attention, you will find that this is very counterintuitive.
you should move the red line half a beat to this position 00:00:615, Then is in line with the rhythm of the song correctly.
Also, you can refer to other ranked versions of this song, they all set the timing point correctly:
