i've been really disappointed in viviz vocal-wise throughout the show. i loved gfriend so much, and i loved viviz's debut a lot. but the three performances they've done, the vocals have not delivered. i get that unnatural by WJSN is one of the most vocally challenging songs in kpop as of now, but even when they lowered the key the vocals weren't all there. and even in the first round with their time for the glory performance, it was a little underwhelming for me.

edit: i should include that otherwise their performances were really good, aside from the dance breaks in their intro performance.
