yo, good job on the vocaloid, the singing fits well with the instrumental which is also pretty neat!
The main criticism I can think of is arrangement related and is that imo the chorus/drop could hit a little harder so there is more of a payoff after the build, you could make the build quieter or the drop louder; for the latter a louder bass/ larger chords/some more layers on the percussion could help with this.
thats the only thing that really stood out, sweet track!
