It's kinda hard for me to judge since the notes aren't properly crossfaded (select all notes and click on either P2P3 or P1P4) making it not blend well and makes transitions less natural than CV voicebanks already are.
Here's a little critique on your tuning:
- Consider well where you place your control points. For example, you place your control point for "ya" and "ri" in your screenshot on C5# and B4. Are there other notes in the UST that are on those pitches? You might want to focus on placing the control points on pitches where other notes in the UST are as they could sound off-pitch otherwise. (this is probably related to music theory but I never looked it up myself so don't trust me this statement)
- Consider well too on the spacing of the control points. The dip in between "ru" and "na" is wide which makes the emphasize of "na" last longer than say the spike you used in "ya". Too wide of a distance can make notes sound offpitch and too short can make them sound robotic
Here's some extra tips:
- Did you use vibrato? They sound great at longer notes or notes at the end of the verse (of course you can put them in between but that's where I mostly put them)
- 2-point pitchbends sound very nice despite being simple. Sloping down pitchbends especially imo
- Here's some good 5-pitch pitchbends that you'd want to use on notes that you want to emphasize a lot
(sorry if this seems messy or makes no sense >.< Tuning is an art and doesn't really have rules, just techniques and "guidelines" to make sure you're not overdoing things)
