[Volume] Some green line's volume jumps a lot to next green line and will give not-intended feedback (low) when player hit early, you may consider move (or add additional green line if kiai or there is SV applied on the spots) 1/4 early with the intended volume to prevent it.
I have just tested some places with volume transition, It wasn't really noticeable for me because it doesn't create a big difference
I don't think the volume increase at the first line is really needed because the volume is as calm as how the section represents now and higher volume is a little too loud
